merge upstream

Existing notes initialised raw markdown mode from note.checklistMode
instead of the defaultNoteMode preference, so users with Markdown as
default always got the rich text editor when reopening a note.

Fixes #96

+### Dark theme
+
+Dark mode overrides every colour variable in `[data-theme="dark"]` (`src/app.css`). It is not a
+mechanical inversion of light mode — two differences are deliberate:
+
+- **`--primary` differs per theme.** `#C8860A` on parchment, `#e0a030` on ink. The light gold reads
+  mustard on a dark background.
+- **`--border` is a warm mid-grey (`#57514b`), not mirrored cream.** A bright 1px line on a dark
+  background reads as glare rather than structure; the hard offset shadow carries the retro framing.
+
+Note colours have two representations, and they are not interchangeable:
+
+| Map | Function | Used by | Role |
+|---|---|---|---|
+| `NOTE_COLORS` / `NOTE_COLORS_DARK` | `getNoteColor(color, isDark)` | Cards, editor, share page | Quiet **surface** you read text on |
+| `NOTE_CHIPS_DARK` | `getNoteChip(color, isDark)` | `ColorPicker` only | Vivid **label** you identify at a glance |
+
+A dark card sits at low lightness, where a 28px picker circle would read as a grey dot — small
+patches lose apparent saturation. Never fill a picker swatch with `getNoteColor()`. In light mode
+`getNoteChip()` returns the pastel card colour, because there the pastels *are* the cards.
+
+When changing any dark note colour, keep the invariants asserted in `src/lib/utils/colors.test.ts`:
+AA contrast (4.5:1) against both `--text` and `--text-muted` on every dark surface, no two dark card
+surfaces closer than an RGB distance of 8, no two dark chips closer than an RGB distance of 25, and
+`getNoteChip()` returning the card colour in light mode but a distinct chip in dark mode.
+
+`--bg-base` is duplicated as a literal in `src/app.html` (FOUC script) and
+`src/lib/utils/theme.svelte.ts` (`DARK_THEME_COLOR`) for the browser theme-colour. Update all three
+together.

+### Admin password resets
+
+An admin can reset the password of any user other than themselves. Crumbs generates the new password and shows it once in that user's row — copy it and pass it to the user out of band, because it is not stored anywhere and cannot be shown again once dismissed. If SMTP is configured Crumbs also tries to notify the user that their password was reset, but the attempt is best-effort: a delivery failure is logged on the server and never surfaced in the UI, so a successful reset is not evidence the user was told. The notification never contains the password.
+
+The control appears on every row, but is unavailable in two cases:
+
+- **Your own row** — change your own password in **Settings > Profile**, which verifies your current password first.
+- **While a generated password is still on screen** — dismiss it first if you need to generate another.
+
+A reset enables password login for that account if it was not already enabled — including OAuth-only accounts — without removing their SSO link. Both sign-in methods can coexist.
+
+A reset **revokes all of the user's sessions** — they must sign in again with the new password (or via OAuth if linked). **Disable password login** is a separate action on rows where password login is enabled; it clears the stored hash, turns off password login, and revokes all sessions. It is not offered on your own row.
+
+A displayed password is only good until that account's password changes again: any later reset — by another admin, or by the user themselves from **Settings > Profile** — silently invalidates one still on screen, and nothing marks it as stale. Separately, if Crumbs cannot confirm a reset it says so and shows the password anyway; keep that one, since it may or may not have been applied, and reset again if the user cannot sign in.
+
+> **No password recovery.** Crumbs has no forgot-password flow. An admin who forgets their own password cannot reset it themselves: the admin control excludes their own row, and the profile flow requires the current password. Another admin can reset you, so keep a second admin account as cheap insurance. Failing that, if an OAuth/SSO provider is configured and your account's email matches your identity there, signing in with that provider gets you back in without a password. An admin can also enable password login on an OAuth-linked account via **Settings > Users**. With no other admin and no provider configured, there is no way back in through the app.

+# Dark Theme Palette Rework Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Replace the dark theme's palette with a systematically generated one, and decouple the colour-picker swatch from the note card surface so the twelve colours are distinguishable.
+
+**Architecture:** Purely a colour-data and CSS-variable change. `NOTE_COLORS_DARK` in `src/lib/utils/colors.ts` gets new values; a new `NOTE_CHIPS_DARK` map plus `getNoteChip()` serves the picker only. The `[data-theme="dark"]` block in `src/app.css` is rewritten. Consumers (`NoteCard`, `NoteEditor`, the public share page) already resolve colour through `getNoteColor()` and need no changes — only `ColorPicker.svelte` switches functions.
+
+**Tech Stack:** SvelteKit + Svelte 5 runes, Tailwind CSS v4, Vitest (unit), Playwright (e2e), pnpm.
+
+**Spec:** `docs/superpowers/specs/2026-07-31-dark-palette-design.md`
+
+## Global Constraints
+
+- Light mode must not change. Any diff touching `NOTE_COLORS` (the light map) or `:root` colour values other than the new `--accent-check` is out of scope.
+- Never hardcode Tailwind colours (`text-gray-500`, `bg-red-600`). Always reference CSS variables. (Project rule, `CLAUDE.md`.)
+- Run `pnpm check` before every commit — not just tests. (Project rule.)
+- Run `pnpm build` before `pnpm test:e2e` locally, or e2e tests run against a stale bundle.
+- Conventional commit prefixes: `feat:`, `fix:`, `chore:`, `docs:`, `refactor:`, `test:`.
+- Exact dark palette values are given verbatim in each task. Do not re-derive or "improve" them — they were generated to hold WCAG AA against `--text` and `--text-muted` on all twelve surfaces, and hand-tweaking breaks that.
+
+---
+
+### Task 1: New dark note-card colours
+
+**Files:**
+- Modify: `src/lib/utils/colors.ts:18-31` (the `NOTE_COLORS_DARK` map)
+- Test: `src/lib/utils/colors.test.ts`
+- Modify: `tests/e2e/public-sharing.spec.ts` (asserted dark `fog` value)
+- Modify: `tests/e2e/dark-mode.spec.ts:84` (stale comment)
+
+**Interfaces:**
+- Consumes: nothing from earlier tasks.
+- Produces: `NOTE_COLORS_DARK` with the values below. `getNoteColor(color: NoteColor, isDark: boolean): string` keeps its existing signature. Task 2 relies on `getNoteColor` being unchanged; Task 2's chip values must differ from every value here.
+
+- [ ] **Step 1: Write the failing invariant tests**
+
+Add to `src/lib/utils/colors.test.ts`. These assert the *properties* that broke, not the hex strings — a hex-only test would have passed happily on the old broken palette.
+
+```ts
+/** WCAG relative luminance. */
+function relativeLuminance(hex: string): number {
+	const n = parseInt(hex.slice(1), 16);
+	const channels = [(n >> 16) & 255, (n >> 8) & 255, n & 255].map((v) => {
+		const s = v / 255;
+		return s <= 0.03928 ? s / 12.92 : Math.pow((s + 0.055) / 1.055, 2.4);
+	});
+	return 0.2126 * channels[0] + 0.7152 * channels[1] + 0.0722 * channels[2];
+}
+
+function contrastRatio(a: string, b: string): number {
+	const [l1, l2] = [relativeLuminance(a), relativeLuminance(b)];
+	return (Math.max(l1, l2) + 0.05) / (Math.min(l1, l2) + 0.05);

+		for (const [name, { bg }] of Object.entries(NOTE_COLORS_DARK)) {
+			expect(contrastRatio(bg, DARK_TEXT_MUTED), `${name} (${bg})`).toBeGreaterThanOrEqual(4.5);
+		}
+	});
+
+	it('holds the twelve surfaces within a narrow lightness band so they read as a family', () => {
+		const luminances = Object.values(NOTE_COLORS_DARK).map((c) => relativeLuminance(c.bg));
+		expect(Math.max(...luminances) - Math.min(...luminances)).toBeLessThan(0.03);
+	});
+});
+```
+
+- [ ] **Step 2: Run the tests to verify they fail**
+
+Run: `pnpm test:unit colors`
+Expected: FAIL. Only the two hex-pinning assertions fail (they still pin the old values). The AA
+tests are forward guards, not regressions of the old palette — the old palette actually clears
+both AA thresholds. The distinguishability test is the one that would fail on the old palette
+(its closest pair, `fog`/`storm`, sits at RGB distance 7.5).
+
+- [ ] **Step 3: Replace the dark palette**
+
+In `src/lib/utils/colors.ts`, replace the whole `NOTE_COLORS_DARK` map with these values exactly:
+
+```ts
+export const NOTE_COLORS_DARK: Record<NoteColor, { bg: string; label: string }> = {
+	default: { bg: '#21201f', label: 'Default' },
+	coral: { bg: '#3f1f1c', label: 'Coral' },
+	peach: { bg: '#3f2b1c', label: 'Peach' },
+	sand: { bg: '#3c371b', label: 'Sand' },
+	mint: { bg: '#2a3d1d', label: 'Mint' },
+	sage: { bg: '#1f3d36', label: 'Sage' },
+	fog: { bg: '#253946', label: 'Fog' },
+	storm: { bg: '#1d283d', label: 'Storm' },
+	dusk: { bg: '#3d2843', label: 'Dusk' },
+	blossom: { bg: '#3d2129', label: 'Blossom' },
+	clay: { bg: '#363126', label: 'Clay' },
+	chalk: { bg: '#303036', label: 'Chalk' }
+};
+```
+
+Note for the implementer: `blossom` and `storm` intentionally shift hue relative to their light counterparts (toward pink and true blue). At higher chroma the original hues collided with `coral`/`peach` and `fog`. This is deliberate — see the spec.
+
+- [ ] **Step 4: Update the two hex assertions that pin the old values**
+
+In `src/lib/utils/colors.test.ts`, the existing `getNoteColor` tests assert old hexes. Change them:
+
+```ts
+	it('returns dark color when isDark is true', () => {
+		expect(getNoteColor('default', true)).toBe('#21201f');
+		expect(getNoteColor('coral', true)).toBe('#3f1f1c');
+	});
+
+	it('returns default color for unknown color name', () => {
+		expect(getNoteColor('unknown' as any, false)).toBe('#faf5eb');
+		expect(getNoteColor('unknown' as any, true)).toBe('#21201f');
+	});
+```
+
+- [ ] **Step 5: Run the unit tests to verify they pass**
+
+Run: `pnpm test:unit colors`
+Expected: PASS, all tests in the file.
+
+- [ ] **Step 6: Update the e2e test that asserts a dark note colour**
+
+`tests/e2e/public-sharing.spec.ts` — the "Shared note follows a dark-mode visitor theme" scenario asserts dark `fog`. `#253946` is `rgb(37, 57, 70)`:
+
+```ts
+		await expect(publicPage.getByTestId('shared-note')).toHaveCSS(
+			'background-color',
+			'rgb(37, 57, 70)'
+		);
+```
+
+In `tests/e2e/dark-mode.spec.ts:84`, the assertion itself is a negative one (`not.toBe` light default) and needs no change, but its comment names the old hex. Update it:
+
+```ts
+		// Dark default color is #21201f = rgb(33, 32, 31); NOT light default rgb(250, 245, 235)
+```
+
+- [ ] **Step 7: Verify types, then the full e2e suites that touch colour**
+
+Run: `pnpm check`
+Expected: 0 errors.
+
+Run: `pnpm build && pnpm test:e2e public-sharing dark-mode organization`
+Expected: PASS. (`organization.spec.ts` exercises the picker but asserts no hex, so it should be unaffected — it is in the list to prove that.)
+
+- [ ] **Step 8: Commit**
+
+```bash
+git add src/lib/utils/colors.ts src/lib/utils/colors.test.ts tests/e2e/public-sharing.spec.ts tests/e2e/dark-mode.spec.ts
+git commit -m "feat(theme): rebuild dark note colours as a consistent family"

+- Produces: `NOTE_CHIPS_DARK: Record<NoteColor, string>` and `getNoteChip(color: NoteColor, isDark: boolean): string`. No later task depends on these.
+
+- [ ] **Step 1: Write the failing tests**
+
+Add to `src/lib/utils/colors.test.ts`:
+
+```ts

+				expect(distance, `${nameA} vs ${nameB}`).toBeGreaterThan(25);
+			}
+		}

+```
+
+Extend the import at the top of the file:
+
+```ts
+import {

+
+- [ ] **Step 2: Run the tests to verify they fail**
+
+Run: `pnpm test:unit colors`
+Expected: FAIL — `getNoteChip is not a function` / `NOTE_CHIPS_DARK` undefined.
+
+- [ ] **Step 3: Add the chip map and accessor**
+
+Append to `src/lib/utils/colors.ts`, after `getNoteColor`:
+
+```ts
+/**
+ * Picker swatches are labels, not surfaces. A 28px circle at card lightness
+ * reads as a grey dot — small patches lose apparent saturation — so the dark
+ * picker uses vivid mid-lightness chips that share the card's hue but not its

+ */
+export const NOTE_CHIPS_DARK: Record<NoteColor, string> = {
+	default: '#8d857c',
+	coral: '#d04f43',
+	peach: '#cd7c42',

+```
+
+- [ ] **Step 4: Run the tests to verify they pass**
+
+Run: `pnpm test:unit colors`
+Expected: PASS.
+
+- [ ] **Step 5: Point the picker at the chips**
+
+In `src/lib/components/ColorPicker.svelte`, change the import on line 2 and the style on line 19:
+
+```svelte
+	import { COLOR_OPTIONS, getNoteChip } from '$lib/utils/colors.js';
+```
+
+```svelte
+			style="background-color: {getNoteChip(option.value, getIsDarkMode())}"
+```
+
+Leave everything else alone — the 2px `--border-subtle` ring stays, and it's what gives each swatch its boundary regardless of fill.
+
+- [ ] **Step 6: Add the e2e scenario**
+
+Append inside the `test.describe.serial('Dark mode', ...)` block in `tests/e2e/dark-mode.spec.ts`:
+
+```ts
+	test('Scenario: Colour picker swatches are identifiable in dark mode', async ({
+		authenticatedPage: page
+	}) => {
+		// Given dark theme is active
+		await page.goto('/settings/preferences');
+		await page.waitForLoadState('networkidle');
+		await page.getByTestId('pref-theme-dark').click();
+		await expect(page.locator('html')).toHaveAttribute('data-theme', 'dark');
+
+		// When the user opens the colour picker while editing a note
+		await page.goto('/');
+		await page.waitForLoadState('networkidle');
+		await page.getByTestId('new-note-btn').click();
+		await page.getByTestId('note-title-input').fill('Swatch Test');
+		await page.getByTestId('color-picker-toggle').click();
+		await expect(page.getByTestId('color-picker')).toBeVisible();
+
+		// Then a swatch shows its vivid chip rather than the muted card surface
+		await expect(page.getByTestId('color-coral')).toHaveCSS(
+			'background-color',
+			'rgb(208, 79, 67)'
+		);
+
+		await page.getByTestId('close-editor-btn').click();
+	});
+```
+
+- [ ] **Step 7: Verify**
+
+Run: `pnpm check`

+
+### Task 3: New dark CSS variables and checkbox accent
+
+**Files:**
+- Modify: `src/app.css:6-24` (`:root` — add `--accent-check` only), `src/app.css:26-42` (the `[data-theme="dark"]` block), `src/app.css:44-48` (`accent-color`)
+
+**Interfaces:**
+- Consumes: nothing. The `--text`/`--text-muted` values here must match the constants asserted in Task 1's tests (`#ece3d3`, `#b3a695`).
+- Produces: `--accent-check` custom property, available in both themes.
+
+- [ ] **Step 1: Add `--accent-check` to `:root`**
+
+In the `:root` block in `src/app.css`, after `--grid-dot`:
+
+```css
+	--grid-dot: #1a1a2e;
+	--accent-check: var(--primary);
+```
+
+- [ ] **Step 2: Replace the dark block**
+
+Replace the entire `[data-theme="dark"]` block with:
+
+```css
+[data-theme="dark"] {
+	--bg-base: #141312;
+	--bg-surface: #1e1c1b;
+	--primary: #e0a030;
+	--primary-hover: #f2b855;
+	--text: #ece3d3;
+	--text-muted: #b3a695;
+	--border: #57514b;
+	--border-subtle: #302d2b;
+	--destructive: #e2705c;
+	--error-bg: #3a2320;
+	--error-border: #5c3a34;
+	--error-text: #f0a898;
+	--success-bg: #1f2e1f;
+	--success-text: #8fc97a;
+	--card-shadow: 2px 2px 0px var(--border-subtle);
+	--card-shadow-hover: 3px 3px 0px var(--primary);
+	--grid-dot: #ece3d3;
+	/* Dimmed so a long done-list of gold checkboxes doesn't shout. */
+	--accent-check: #c8a44a;
+}
+```
+
+Two of these reverse earlier decisions on purpose: `--primary` is no longer shared with light mode (`#C8860A` reads mustard on ink), and `--border` is a warm mid-grey rather than the mirrored cream `#e8dcc8` (a bright 1px line on a dark background reads as glare, not structure).
+
+- [ ] **Step 3: Point `accent-color` at the new variable**
+
+In the `html, body` rule:
+
+```css
+html, body {
+	font-family: 'JetBrains Mono', monospace;
+	accent-color: var(--accent-check);
+	overscroll-behavior-y: none;
+}
+```
+
+- [ ] **Step 4: Verify light mode is untouched and dark mode renders**
+
+Run: `pnpm check`
+Expected: 0 errors.
+
+Run: `pnpm build && pnpm test:e2e dark-mode public-sharing`
+Expected: PASS. Task 1's e2e assertions cover the dark note colours; nothing asserts the chrome variables, so this step is proving no regression rather than proving the change.
+
+Then look at it: `pnpm preview`, open the app, switch to dark in Settings → Preferences, and check the notes grid, the sidebar, an open editor, and a checklist with done items. Contrast maths can't judge the pixel-grid overlay or the gold hover states.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/app.css
+git commit -m "feat(theme): replace dark surfaces, borders and accents with the warm ink palette"
+```
+
+---
+
+### Task 4: Sync the browser theme-colour with the new base
+
+**Files:**
+- Modify: `src/lib/utils/theme.svelte.ts:4`
+- Modify: `src/app.html:21`
+- Test: `src/lib/utils/theme.test.ts:40`
+
+**Interfaces:**
+- Consumes: `--bg-base` `#141312` from Task 3. These two hardcoded copies must equal it.
+- Produces: nothing.
+
+- [ ] **Step 1: Update the failing test first**
+
+In `src/lib/utils/theme.test.ts`:
+
+```ts
+	it('updates meta theme-color for dark mode', () => {
+		applyTheme('dark');
+		const meta = document.querySelector('meta[name="theme-color"]');
+		expect(meta?.getAttribute('content')).toBe('#141312');
+	});
+```
+
+- [ ] **Step 2: Run it to verify it fails**
+
+Run: `pnpm test:unit theme`
+Expected: FAIL — received `#1a1715`.
+
+- [ ] **Step 3: Update both hardcoded copies**
+
+`src/lib/utils/theme.svelte.ts` line 4:
+
+```ts
+const DARK_THEME_COLOR = '#141312';
+```
+
+`src/app.html` line 21, inside the FOUC script:
+
+```js
+            if (m) m.content = '#141312';
+```
+
+- [ ] **Step 4: Run the test to verify it passes**
+
+Run: `pnpm test:unit theme`
+Expected: PASS.
+
+- [ ] **Step 5: Verify and commit**
+
+Run: `pnpm check && pnpm test:unit`
+Expected: 0 errors, all unit tests pass.
+
+```bash
+git add src/lib/utils/theme.svelte.ts src/app.html src/lib/utils/theme.test.ts
+git commit -m "fix(theme): sync browser theme-colour with the new dark base"
+```
+
+---
+
+### Task 5: Document the palette
+
+**Files:**
+- Modify: `CLAUDE.md` (the "Design system: Retro Parchment" section)
+- Modify: `docs/ARCHITECTURE.md:155-165` (the dark mode section)
+
+**Interfaces:**
+- Consumes: everything from Tasks 1-4.
+- Produces: nothing.
+
+- [ ] **Step 1: Document the dark palette in `CLAUDE.md`**
+
+The colour table there lists only light values, which is why the dark palette drifted in the first place. After the existing table and the note about `src/lib/utils/colors.ts`, add:
+
+```markdown
+### Dark theme
+
+Dark mode overrides every colour variable in `[data-theme="dark"]` (`src/app.css`). It is not a
+mechanical inversion of light mode — two differences are deliberate:
+
+- **`--primary` differs per theme.** `#C8860A` on parchment, `#e0a030` on ink. The light gold reads
+  mustard on a dark background.
+- **`--border` is a warm mid-grey (`#57514b`), not mirrored cream.** A bright 1px line on a dark
+  background reads as glare rather than structure; the hard offset shadow carries the retro framing.
+
+Note colours have two representations, and they are not interchangeable:
+
+| Map | Function | Used by | Role |
+|---|---|---|---|
+| `NOTE_COLORS` / `NOTE_COLORS_DARK` | `getNoteColor(color, isDark)` | Cards, editor, share page | Quiet **surface** you read text on |
+| `NOTE_CHIPS_DARK` | `getNoteChip(color, isDark)` | `ColorPicker` only | Vivid **label** you identify at a glance |
+
+A dark card sits at ~18% lightness, where a 28px picker circle would read as a grey dot — small
+patches lose apparent saturation. Never fill a picker swatch with `getNoteColor()`. In light mode
+`getNoteChip()` returns the pastel card colour, because there the pastels *are* the cards.
+
+When changing any dark note colour, keep the invariants asserted in `src/lib/utils/colors.test.ts`:
+AA contrast against both `--text` and `--text-muted` on every surface, a narrow lightness band across
+the twelve, and no two chips closer than an RGB distance of 25.
+
+`--bg-base` is duplicated as a literal in `src/app.html` (FOUC script) and
+`src/lib/utils/theme.svelte.ts` (`DARK_THEME_COLOR`) for the browser theme-colour. Update all three
+together.
+```
+
+- [ ] **Step 2: Update `docs/ARCHITECTURE.md`**
+
+In the dark mode section, the line describing note colours currently mentions only `getNoteColor()`. Replace it with:
+
+```markdown
+- **Note card colors**: `getNoteColor()` in `src/lib/utils/colors.ts` accepts a `dark` boolean and
+  returns the appropriate surface variant per theme. Picker swatches use `getNoteChip()` instead —
+  in dark mode the card surfaces are too dark to be identifiable as small circles, so the picker
+  draws from a separate vivid `NOTE_CHIPS_DARK` map.
+```
+
+- [ ] **Step 3: Verify the docs match the code**
+
+Re-read both edited sections against `src/lib/utils/colors.ts` and `src/app.css`. Every function name, map name, file path and hex value must exist as written. No verification command can catch a wrong hex in prose — check it by eye.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add CLAUDE.md docs/ARCHITECTURE.md
+git commit -m "docs: document the dark palette and the card-vs-chip distinction"
+```
+
+---
+
+## Final verification
+
+- [ ] `pnpm check` — 0 errors
+- [ ] `pnpm test:unit` — all pass
+- [ ] `pnpm build && pnpm test:e2e` — full suite passes

+# Dark Theme Palette Rework — Design Spec
+
+**Date:** 2026-07-31
+**Status:** Approved
+**Supersedes the palette portion of:** `2026-03-20-dark-mode-design.md`
+
+## Summary
+
+The dark theme's colours were authored one at a time rather than as a set. The result: twelve note
+colours that collapse into indistinguishable dark mud, a picker of twelve grey dots, sepia-tinted
+surfaces, and a near-white editor outline that reads as glare. This spec replaces the dark palette
+with a systematically generated one, and splits the picker swatch from the card surface — they are
+different jobs and should not share a value.
+
+Light mode is unchanged.
+
+## Problems being fixed
+
+1. **Note colours are indistinguishable.** `coral #4a2522`, `peach #4a3020` and `clay #302e28` differ
+   by a few percent lightness with almost no chroma. Lightness wanders across the set (17%–19%) with
+   no consistent relationship, so they don't read as a family.
+2. **Several cards don't separate from the page.** `clay`, `chalk` and `default` sit within a few
+   percent of `--bg-base`, so cards lose their edges.
+3. **The picker is unreadable.** `ColorPicker.svelte` fills each swatch with the card background. A
+   28px circle at 18% lightness cannot read as a colour — small patches lose apparent saturation, so
+   twelve swatches become twelve grey dots.
+4. **Surfaces are sepia.** `--bg-base #1a1715` / `--bg-surface #2a2520` are brown-tinted; combined
+   with gold and cream on top, the UI reads dim rather than crisp.
+5. **The editor frame glares.** `--border` mirrors light mode's near-black ink as near-white cream.
+   The mirror is false: dark-on-light edges absorb, light-on-dark edges emit. At equal contrast the
+   inverted border reads as a glowing rectangle, not as structure.
+
+## Decisions
+
+| # | Decision | Choice |
+|---|---|---|
+| 1 | Base surfaces | **Warm ink** — pull the brown out, keep a trace of warmth |
+| 2 | Card lightness | **Deep tinted (~18%)** — colours identifiable, page still reads dark |
+| 3 | Picker swatches | **Vivid mid-lightness chips**, decoupled from the card colour |
+| 4 | Chip scope | **Dark mode only** — light mode keeps its pastel swatches |
+| 5 | Chrome | **Quiet frame** — `--border` becomes warm mid-grey, not cream |
+
+On (4): in light mode the pastels genuinely *are* the card colours, so they preview correctly there.
+Only dark mode needs the split.
+
+## 1. CSS variables (`src/app.css`)
+
+Replace the `[data-theme="dark"]` block:
+
+```css
+[data-theme="dark"] {
+  --bg-base: #141312;
+  --bg-surface: #1e1c1b;
+  --primary: #e0a030;
+  --primary-hover: #f2b855;
+  --text: #ece3d3;
+  --text-muted: #b3a695;
+  --border: #57514b;
+  --border-subtle: #302d2b;
+  --destructive: #e2705c;
+  --error-bg: #3a2320;
+  --error-border: #5c3a34;
+  --error-text: #f0a898;
+  --success-bg: #1f2e1f;
+  --success-text: #8fc97a;
+  --card-shadow: 2px 2px 0px var(--border-subtle);
+  --card-shadow-hover: 3px 3px 0px var(--primary);
+  --grid-dot: #ece3d3;
+  --accent-check: #c8a44a;
+}
+```
+
+Three of these are notable changes rather than tweaks:
+
+- **`--primary` is no longer shared across themes.** `#C8860A` was chosen for parchment; on ink it
+  reads mustard. Dark mode gets `#e0a030` (8.17:1 on the page).
+- **`--border` becomes `#57514b`** instead of cream `#e8dcc8`. Frames the editor without glare; the
+  hard offset shadow still carries the retro structure.
+- **`--text-muted` lifts `#9a8e7e` → `#b3a695`.** Required for AA on the tinted cards. This is the
+  widest-reaching change in the spec — every muted element in dark mode shifts slightly.
+
+### Checkbox accent
+
+`accent-color: var(--primary)` makes a long done-list shout in dark mode. Add a dedicated variable so
+the checkbox can be dimmed independently of links and the brand:
+
+```css
+:root { --accent-check: var(--primary); }   /* light: unchanged */
+html, body { accent-color: var(--accent-check); }
+```
+
+## 2. Note card colours (`src/lib/utils/colors.ts`)
+
+Replace `NOTE_COLORS_DARK`. Every entry keeps its light counterpart's hue, holds lightness
+near-constant against today's values (measured average change: +4.1 saturation points, −0.18
+lightness points), and nudges two crowded hues apart (`blossom` and `storm` shift toward pink
+and true blue respectively) so the twelve read as distinguishable siblings rather than a smudge.
+The visible improvement in dark mode comes from the base surfaces, the picker chips, the
+softened border, and the lifted gold — not from the card surfaces, which are close in chroma to
+the previous dark values.
+
+```ts
+export const NOTE_COLORS_DARK: Record<NoteColor, { bg: string; label: string }> = {
+  default: { bg: '#21201f', label: 'Default' },
+  coral:   { bg: '#3f1f1c', label: 'Coral' },
+  peach:   { bg: '#3f2b1c', label: 'Peach' },
+  sand:    { bg: '#3c371b', label: 'Sand' },
+  mint:    { bg: '#2a3d1d', label: 'Mint' },
+  sage:    { bg: '#1f3d36', label: 'Sage' },
+  fog:     { bg: '#253946', label: 'Fog' },
+  storm:   { bg: '#1d283d', label: 'Storm' },
+  dusk:    { bg: '#3d2843', label: 'Dusk' },
+  blossom: { bg: '#3d2129', label: 'Blossom' },
+  clay:    { bg: '#363126', label: 'Clay' },
+  chalk:   { bg: '#303036', label: 'Chalk' }
+};
+```
+
+**Two hues are deliberately nudged apart.** At low chroma, `coral`/`peach`/`blossom` are three
+barely-different oranges and `fog`/`storm` are two barely-different blues — invisible in light mode,
+but they collide once chroma rises. So in dark mode `blossom` moves toward pink (H344) and `storm`
+toward true blue (H218). Their light-mode values are untouched, so the same note is a slightly
+different hue in each theme. This is an accepted trade: distinguishable beats identical.
+
+Measured on these values: body text ≥ 9.25:1, muted text ≥ 4.94:1, links ≥ 5.18:1 on every card.
+All clear WCAG AA.
+
+## 3. Picker chips (`src/lib/utils/colors.ts`)
+
+New map, used only by the picker, only in dark mode:
+
+```ts
+export const NOTE_CHIPS_DARK: Record<NoteColor, string> = {
+  default: '#8d857c', coral: '#d04f43', peach: '#cd7c42', sand:  '#c7b138',
+  mint:    '#7bbd4c', sage:  '#47b89d', fog:   '#609abe', storm: '#547bc0',
+  dusk:    '#a965bd', blossom: '#c05d78', clay: '#b5954a', chalk: '#c3c3c8'
+};
+
+/** Picker swatch colour: a vivid label, not the card surface. */
+export function getNoteChip(color: NoteColor, isDark: boolean): string {
+  if (!isDark) return getNoteColor(color, false);   // light mode: pastel == card
+  return NOTE_CHIPS_DARK[color] ?? NOTE_CHIPS_DARK.default;
+}
+```
+
+`default` and `chalk` stay deliberately neutral (grey and off-white) — they are the "no colour"
+slots. Chips are non-text UI, so WCAG's bar is 3:1, not 4:1; every chip clears that comfortably
+against `--bg-surface`, with the lowest at `coral` 3.95:1 (`storm` 4.02:1, `blossom` 4.10:1). The
+closest pair (`fog`/`storm`) is separated by an RGB distance of 33, which is comfortably tellable
+apart at 28px.
+
+`ColorPicker.svelte` switches from `getNoteColor` to `getNoteChip`. Nothing else uses chips — cards,
+the editor and the public share page keep calling `getNoteColor`.
+
+## 4. Theme-colour meta tag
+
+`#1a1715` is hardcoded in two places that must stay in sync with `--bg-base`:
+
+- `src/app.html` (the FOUC script, `m.content = '#1a1715'`)
+- `src/lib/utils/theme.svelte.ts` (`DARK_THEME_COLOR`)
+
+Both become `#141312`.
+
+## Files to modify
+
+| File | Change |
+|---|---|
+| `src/app.css` | Rewrite `[data-theme="dark"]`; add `--accent-check` to `:root`; point `accent-color` at it |
+| `src/lib/utils/colors.ts` | New `NOTE_COLORS_DARK`; add `NOTE_CHIPS_DARK` + `getNoteChip()` |
+| `src/lib/components/ColorPicker.svelte` | Use `getNoteChip()` instead of `getNoteColor()` |
+| `src/app.html` | Theme-colour `#1a1715` → `#141312` |
+| `src/lib/utils/theme.svelte.ts` | `DARK_THEME_COLOR` → `#141312` |
+| `src/lib/utils/colors.test.ts` | Update dark `default` assertions; add `getNoteChip` coverage |
+| `src/lib/utils/theme.test.ts` | Update theme-colour assertion |
+| `tests/e2e/dark-mode.spec.ts` | Update asserted dark default `rgb(42,37,32)` → `rgb(33,32,31)` |
+| `tests/e2e/public-sharing.spec.ts` | Update asserted dark `fog` `rgb(34,46,58)` → `rgb(37,57,70)` |
+| `CLAUDE.md` | Document the dark palette and the card-vs-chip distinction in the design system section |
+| `docs/ARCHITECTURE.md` | Update the dark mode section for `getNoteChip` |
+
+Nothing needs to change in `NoteCard`, `NoteEditor`, or the share page — they already resolve colour
+through `getNoteColor`, so they inherit the new palette.
+
+## Testing
+
+**Unit (`colors.test.ts`)** — the palette is data, so test its invariants rather than its hex values:
+
+- `getNoteChip(c, false)` equals `getNoteColor(c, false)` for all twelve (light mode is unchanged)
+- `getNoteChip(c, true)` differs from `getNoteColor(c, true)` for all twelve (chip ≠ surface)
+- unknown colour falls back to `default` in both maps
+- every dark card holds ≥ 4.5:1 against `--text-muted #b3a695` — this is the invariant that broke
+  before, so it gets asserted rather than eyeballed
+- no two dark chips are within an RGB distance of 25 (guards the crowded-hue regression)
+
+**E2E (`dark-mode.spec.ts`)** — extend the existing "note cards use dark colors" scenario to assert a
+picker swatch is *not* the card background, which is the bug in user-visible terms.
+
+**Manual** — the pixel-grid overlay and gold hover states want a real look on device; contrast maths
+can't judge those.
+
+## Out of scope
+
+- Light mode, including its picker
+- The 12-colour set itself (no colours added, removed, or renamed)
+- Per-note custom colours
+- `prefers-contrast` / high-contrast variants

+# Note Linking — Design Spec
+
+**Issue**: [#74 — feat: link to other crumbs (notes) inside the app](https://github.com/bretzel-app/crumbs/issues/74)
+**Date**: 2026-08-03
+
+## Overview
+
+Let a note reference another note by ID, so clicking it opens the target note in the editor. Reuses the existing "insert link" toolbar entry point (Ctrl+K) rather than introducing a new `[[wikilink]]`-style typing syntax. The displayed link text always tracks the target note's current title — it's a live reference, not frozen text — and the target note gets a "Referenced by" backlinks section.
+
+## Decisions
+
+| Decision | Choice | Rationale |
+|---|---|---|
+| Link creation UX | Extend the existing link toolbar dropdown with a note-search mode | Matches the issue reporter's own proposed solution; reuses the Link dropdown, `/api/search`, and toolbar infra as-is instead of building a new inline autocomplete |
+| Click behavior | Opens the target note in the editor overlay, same as clicking a note card | Matches how every other note-opening interaction already works in the app |
+| Link label | Always the target note's live title | A stale link label after a rename would be confusing; this requires modeling the link as an atomic node rather than a mark (see Architecture) |
+| Broken/inaccessible links | Grey out, inert, content untouched | Nothing is silently rewritten; if the note is restored from trash the link works again automatically |
+| Backlinks | Included in v1 | Requested explicitly; reuses the same extract-and-sync pattern tags already use, so the incremental cost is a reverse query, not new infrastructure |
+| Public share page | Note-links never resolve, even if the target is also shared | Simplest, most conservative option — zero chance of leaking the existence of a private note to an anonymous visitor |
+| Link picker scope | Owned notes + notes shared with you | Same visibility scope the main notes list already uses; `searchNotes()` already implements this |
+| Removing an existing link | Hover-reveal a small × on the chip | Click already navigates instantly, so it can't also open an edit/remove popover the way external links do; a hover-revealed remove button solves this without touching the click behavior. Repointing a link is just remove + re-insert — no separate "edit target" UI |
+
+## Architecture
+
+**Data model** — a new self-referential join table, mirroring `noteTags`/`tags`:
+
+```typescript
+export const noteLinks = sqliteTable(
+  'note_links',
+  {
+    sourceNoteId: text('source_note_id')
+      .references(() => notes.id, { onDelete: 'cascade' })
+      .notNull(),
+    targetNoteId: text('target_note_id')
+      .references(() => notes.id, { onDelete: 'cascade' })
+      .notNull()
+  },
+  (table) => [
+    index('note_links_source_idx').on(table.sourceNoteId),
+    index('note_links_target_idx').on(table.targetNoteId)
+  ]
+);
+```
+
+**Markdown representation** — a note-link round-trips through raw markdown as a normal-looking link with a custom URI scheme:
+
+```
+[Grocery List](crumb-note://<note-id>)
+```
+
+This keeps the existing raw-markdown-mode toggle showing something readable, and keeps exported/copied content sensible outside the app. The title baked into the markdown text is only ever a fallback for external tools — inside the app, parsing recognizes the `crumb-note://` scheme and rebuilds the live node, discarding whatever static text was there.
+
+**Editor node** — a new tiptap **node** (not a mark) named `NoteLink`, with a single attribute `{ noteId: string }`. Unlike a mark, a node fully owns its own rendering, which is what makes "always show the live title" possible — a mark decorates existing typed text and has no clean way to swap that text later.
+
+## Components
+
+### Client
+
+| Component | Change |
+|---|---|
+| `src/lib/components/tiptap/NoteLink.ts` (new) | Inline atomic tiptap node extension. `NodeView` looks up the target's title via `getNote(id)` from `src/lib/sync/idb.ts` — **not** the reactive `notes` writable store, which only holds whatever the current filter (all/archived/trashed) last loaded and would wrongly grey out a valid note just because it's outside the current view. IndexedDB is kept complete for all accessible notes by the existing `/api/sync` incremental sync, independent of which filter is on screen, so it's the correct source of truth here — and it works offline too. Renders a chip (note icon + title), greys out and disables click if the note isn't found. Click opens the note editor overlay for that ID. A small × button is layered on the chip using the app's existing hover-action pattern (`max-md:opacity-100 md:opacity-0 transition-opacity md:group-hover:opacity-100` — always visible on touch, hover-revealed on desktop) that deletes the node from the document without navigating; there's no separate "change target" action, since deleting and re-inserting is simple enough that a dedicated repoint UI isn't worth building. |
+| `src/lib/components/TiptapEditor.svelte` | Register the `NoteLink` node extension alongside the existing ones. |
+| `src/lib/components/FormattingToolbar.svelte` | The existing link dropdown gets a note-search results list below the URL input, live-filtered by whatever's typed there (debounced, via `/api/search`, excluding the currently-open note) — no heuristic needed to guess whether the typed text is a URL or a note search; both affordances are just available side by side. Applying the URL input still applies the normal external `Link` mark; picking a search result instead inserts a `NoteLink` node at the cursor (replacing any selection). |
+| `src/lib/components/NoteEditor.svelte` | New "Referenced by" section, shown when `note.backlinks` is non-empty — a small chip list near where tags render, each chip opens that referencing note. |
+
+### Server
+
+| Function | Location | Description |
+|---|---|---|
+| `extractNoteLinks(content): string[]` | `src/lib/utils/note-links.ts` (new) | Regex-extracts `crumb-note://<id>` references from markdown content, same code-block/URL exclusions `extractTags` already applies. |
+| `syncNoteLinks(db, noteId, targetIds, userId)` | `src/lib/server/note-links.ts` (new) | Mirrors `syncNoteTags`: clears existing rows for the note, re-inserts the current set, within the same save transaction. |
+| `fetchBacklinksForNote(db, noteId, userId)` | `src/lib/server/note-links.ts` (new) | Reverse query on `noteLinks.targetNoteId`, joined through the same access rules as everything else (owner or collaborator on the *source* note), returning `{id, title}` pairs. |
+
+`getNote()` in `notes-service.ts` calls `fetchBacklinksForNote` and attaches the result as `backlinks`. This is **not** added to `hydrateNotes()` (which also backs list views) — computing backlinks for every note in a list load would be wasted work for something only the open editor displays.
+
+## Data Flow
+
+1. **Create** — pick a note in the toolbar's link dropdown → a `NoteLink` node is inserted at the cursor.
+2. **Save** — content round-trips to markdown as usual; the note-save transaction additionally runs `extractNoteLinks` + `syncNoteLinks`, alongside the existing tag sync.
+3. **Reopen** — markdown parses back into the doc; a custom parse rule recognizes `crumb-note://` and produces a `NoteLink` node; its `NodeView` looks up the live title via IndexedDB (`getNote(id)`), not the filter-scoped reactive store (see Components).
+4. **Click** — opens the target note in the editor overlay.
+5. **Rename** — no action needed anywhere: the title is looked up live at render time, so the next render already shows the new title.
+6. **Trash / permanent delete / no access** — all three are treated identically: the note simply isn't found in IndexedDB (or, server-side, fails the backlink query's access check), so the link renders inert. The referencing note's content is never rewritten.
+7. **Public share page** — doesn't use the tiptap editor; content is rendered server-side via `markdown-it`. That render path strips `crumb-note://` links down to plain, non-clickable text, regardless of whether the target is also shared.
+
+## Error Handling
+
+- **Malformed `crumb-note://` reference** during markdown parse falls back to plain text rather than crashing the parse.
+- **Search race conditions** in the toolbar's note-picker are debounced and guarded against stale results overwriting newer ones, same pattern the existing search feature (`tests/e2e/search.spec.ts`) already covers.
+- **Self-links** — the currently-open note is filtered out of its own picker results.
+- **Circular references** (A ↔ B) are a non-issue — clicking only ever opens one note at a time, nothing recurses.
+- **Cross-user link privacy** — the picker only offers notes you can already access, so under normal use a link can only point at something you had legitimate access to when you created it. Hand-editing raw markdown with a guessed note ID is the only way around that, and note IDs are unguessable UUIDs — the same "if you have the ID, you were meant to have it" trust model the app already applies to session/share tokens. Accepted as a low-severity edge case rather than adding extra access-control plumbing for it.
+
+## Testing
+
+**Unit (Vitest)**
+- `extractNoteLinks` — extracts IDs, ignores code blocks/URLs, dedupes, handles empty content
+- `syncNoteLinks` — clears + re-inserts correctly
+- `fetchBacklinksForNote` — returns only notes the requesting user can access
+- Markdown round-trip — a `NoteLink` node serializes to `[title](crumb-note://id)` and parses back to the same node with the right `noteId`
+
+**E2E (Playwright)**
+- Linking to a note from the toolbar renders a live chip; clicking it opens that note
+- Renaming the linked note updates the displayed link text next time it's viewed
+- A link to a trashed/deleted/inaccessible note renders inert and doesn't navigate
+- The linked-to note shows a "Referenced by" backlink to the note that links to it
+- A public share page never renders a note-link as clickable, even if the target is also shared
+- The note-picker excludes the currently-open note from its own search results
+- Hovering a note-link chip reveals a × button that removes it from the document without navigating; the × is always visible (not hover-gated) on touch devices
+
+## Out of Scope (v1)
+
+- Inline `[[wikilink]]`/`@mention` autocomplete while typing (toolbar-only for now; can be added later without touching the data model)
+- Note graph / visual map view
+- Ranking or sorting backlinks beyond simple list order
+- Cross-user access-control tightening for hand-crafted `crumb-note://` references (see Error Handling)
+
+## Acceptance Criteria
+

+- [ ] Picking a note inserts a live `NoteLink` node showing the target's current title
+- [ ] Clicking a note-link opens the target note in the editor overlay
