Wires the dark-mode plumbing:
- New $lib/theme module: themePreference + resolvedTheme stores plus
initTheme() / setThemePreference(). Owns localStorage persistence,
<html data-theme=...> mirroring, and the matchMedia listener that
re-resolves "system" when the OS preference flips. Storage-agnostic
(no Supabase coupling) so the caller persists to public.users.theme
separately.
- Inline anti-FOUC script in app.html reads localStorage + matchMedia
synchronously and writes data-theme before the first paint — refresh
in dark mode no longer flashes white.
- Tailwind switched to darkMode: ['selector', '[data-theme="dark"]']
so all existing `dark:` utilities resolve from the same attribute.
- :root and :root[data-theme=light] share the light token set; dark
tokens move into :root[data-theme=dark]. Tokens stay as RGB triplets
(rgb(var(--token) / <alpha>)) per the repo gotcha — no hsl().
- ThemeToggle.svelte: three-way radiogroup (Light / Dark / System) with
paraglide messages in EN + ES.
Tests (TDD): 8 new unit specs in src/lib/theme.test.ts cover defaults,
localStorage round-trip, data-theme reflection, system resolution
against matchMedia, invalid-value fallback, and OS preference change
propagation.

- Remove all 1px border separators (sidebar border-r, page header border-b,
section border-t, member list divide-y, invite card border). Separation is
now achieved via background color shifts and whitespace per the "No-Line" rule.
- Fix sidebar: bg-surface-raised vs bg-background creates tonal separation.
- Correct dark background to #020617 (slate-950) per spec.
- Add surface-container-low, text-primary/secondary/muted, destructive tokens.
- Fix CSS variable color space: all tokens are RGB triplets; switch Tailwind
config and app.css from hsl() to rgb() to prevent yellow/warm color bleed.
- Replace emoji nav icons with Lucide icons at 16px / 1.5 stroke-width.
- Apply Masthead typography (uppercase Label-MD + Title-LG) to all page headers
and section labels across lists, tasks, notes, search, settings, manage.
- Destructive action (sign out) uses bg-destructive per spec.
- Add `just serve` command: builds and runs the prod Node server at :3000
against the dev Docker stack for production build testing.
- Add nav_collective i18n key (en + es).
