Serve surfaces/shell's built Dashboard from apps/api on the same origin
as /api (ADR 0044), exactly as the display host is served: a closed set
of files read once at startup, never a static directory, never a path
built from request input.
- The shell exports @ekklesia/shell/dashboard-assets (the exact built
index.html and script URLs), emits the script at
assets/ekklesia-dashboard/app.js, and index.html names that absolute
path so dev and production serve the same URLs.
- GET / and GET /assets/ekklesia-dashboard/app.js answer from a frozen
snapshot: no-cache with a strong ETag and 304 on match. Source maps
are never served; every other path is the ordinary sanitized 404.
- The page sets nosniff, X-Frame-Options: DENY, Content-Security-Policy:
frame-ancestors 'none' (that directive only), and Referrer-Policy:
no-referrer, on 200 and 304 alike.
- A missing or empty shell build fails startup with a fixed
DashboardHostAssetError before any module code is imported.
- The If-None-Match comparison moves to conditional-request.ts, shared
with the display host routes.
- The emailed-link token stripping moves from browser/main.tsx into
consumeAuthLanding (location and history injected) so it is tested;
behavior is unchanged.
