## Slice A — explicit dark/light toggle
projax now ships with two palettes and a 1y cookie to remember the choice.
Dark is the new default; ☀ button in the header nav flips to light and
writes projax_theme=light. Server reads the cookie via themeFromRequest(r)
and injects Theme + ThemeColor into every template via the centralised
render(w, r, …) path, so first paint never flashes the wrong theme. Inline
JS in layout.tmpl handles the toggle without a server roundtrip.
Every panel colour now lives in a CSS variable under
:root[data-theme=dark|light]; the only hardcoded hex values left are
inside those two :root blocks. A future palette tweak is one edit, not
30 selectors. Graph node colours, kind-badges, highlights and warn/ok/bad
all have parallel dark/light values picked for contrast.
Standalone SVG download bakes the light palette inline because the
downloaded asset has no parent :root providing vars — m's existing
snapshots stay print-friendly regardless of his current cookie.
Login page keeps its embedded dark CSS — it's the gateway, intentionally
always dark.
Tests: TestThemeDefaultIsDark, TestThemeCookieRoundTrips,
TestThemeCookieUnknownFallsBackToDark, TestThemeTogglePagesShareSameTheme,
TestThemeToggleScriptPresent, TestThemeColorMetaHelper. Full suite green.
## Slice B — file-upload permanently out of scope (m, 2026-05-17)
docs/design.md moves "File uploads / in-projax storage" from the §3c
parked list to a permanent "Out of scope (decided 2026-05-17)" clause
with the rationale: PER is the cross-reference index, not the file
system. docs/standards/per.md gains the same explicit clause so future
shifts working from the PER standard see the constraint where they
look. Memory note filed so future workers don't re-propose multipart
uploads, attachments tables, or documents buckets.
## docs/design.md §13 Theming
Documents the toggle approach, cookie semantics, palette table, the
standalone-SVG carve-out, the login-page exception, and the 4b
out-of-scope (prefers-color-scheme detection, per-page overrides,
transitions on swap).
The three admin pages (classify, caldav, bulk) had no shared entry point —
m navigated around and couldn't find them. /admin is now their index:
- 3 cards, each linking to the underlying tool, with live counts
(orphan count via projax.items_unified predicate; calendar count via
ListCalendars; item count via projax.items where deleted_at IS NULL
AND archived = false)
- CalDAV card auto-disables when DAV_URL isn't configured
- System panel: version (build-time ldflags hook), last migration
(projax.schema_migrations top row), MCP status (token present
yes/no — token itself never displayed), upstream health (DAV +
Gitea + Supabase, parallel-probed with 1s HTTP timeout each,
cached 30s)
web/admin.go houses the handler + cache + probeURL helper + count
queries. Templates/admin.tmpl renders the cards + system grid.
admin_test.go covers /admin render + nav-link presence on every
chrome-bearing route.
Nav consolidation: the three separate admin links in layout.tmpl
collapse to one /admin entry. Pre-existing TestTreeRenders updated
to assert the new shape.
Probe-URL caveat: probeURL counts any HTTP response as "alive" (incl.
4xx) — the admin panel measures reachability, not authorisation. CalDAV
returns 401 on bare GET; Gitea returns 200 at the root; Supabase same.
All show green when alive.
