Stage 1 PR 6 (ADR 0062). /account shows who is signed in; /account/appearance
chooses System, Light, or Dark and reduced motion (System, Reduce, Allow).
- Core: ekklesia_core_user_preference, one typed, CHECK-constrained,
nullable column per preference (null = never chosen), migration
0008_user_preferences (additive), @ekklesia/core/account store, and the
authenticated-baseline permission core.account.self.manage.
- API: GET /api/v1/account (name, email, preferences) and partial
PATCH /api/v1/account/preferences, self-only by construction: no user id
is accepted anywhere; trusted Origin and body limit on the mutation.
- Shell: the account control shows name, email, and initials (never the
unvetted image URL) and offers Account, Appearance, Sign out; native
radio groups apply a choice at once through the ADR 0060 controller and
save it; the server's answer wins and a failed save reverts.
- First paint: a classic, same-origin, render-blocking appearance.js in
<head> applies a two-word localStorage cache before paint (no inline
script, CSP unchanged). The account replaces the cache on every load,
sign-out clears it, and other tabs follow via the storage event.
- Deploy smoke: real-Chromium checks for light/dark, OS emulation,
overrides, reload persistence, pre-paint, Shadow DOM modules, reduced
motion, the display staying light, and phone width; the browser
container gets a 512 MiB /dev/shm so a long session no longer fails
requests with ERR_INSUFFICIENT_RESOURCES.
