Every reload of a cached files. image failed in the browser with
ERR_HTTP2_PROTOCOL_ERROR. A browser revalidates a cached signed URL
with If-None-Match. Caddy reached SeaweedFS over HTTP/2, and there
SeaweedFS answers with a 304 declaring content-type: application/xml
and content-length: 327 while sending no body. Caddy then logged
"aborting with incomplete response ... unexpected EOF" and reset the
stream. Over HTTP/1.1 SeaweedFS's 304 is clean. Measured layer by layer:
DevTools, curl through Caddy, and curl direct over HTTP/1.1 and HTTP/2.

The storage upstream is now HTTP/1.1 only (`versions 1.1`). Browsers
still reach the proxy over HTTP/2 and HTTP/3.

Delivery-layer CORS is the deployment's, so it no longer depends on
which S3 backend is behind it. SeaweedFS's default reflected any origin
and advertised PUT, POST and DELETE. Now the proxy:
- grants CORS only to the origins that read objects with fetch(): the
  Ekklesia origin, or, when split, the API origin (displays) and the
  Dashboard origin (a module's preview caches images through fetch());
- allows GET and HEAD only, with Vary: Origin;
- answers preflights itself, so they never reach storage;
- strips the object store's own CORS headers.

The deploy README documents the policy, its reasons, and what a
self-run proxy must do.

ekklesiaandClaude Opus 5.5 f63f80f2f0 feat: support split Dashboard and API origins (ADR 0045)

An installation can now serve the Dashboard and the API on sibling
hostnames (dash./api.) beside the default same-origin topology, from one
image and with configuration alone.

- The Dashboard learns its API origin at run time: the built page carries
  one empty <meta name="ekklesia-api-origin">, which the API fills with its
  identity base URL's origin at startup, before computing the page's ETag.
  The shell accepts only a canonical http(s) origin and otherwise fails
  closed without making a request. The build-time EKKLESIA_API_BASE_URL is
  gone from the bundle; the development server injects the same element.
- The display host stays on the API's origin, so its device cookies,
  requests, and offline cache are unchanged.
- The API trusts its own origin (trusted origins plus the identity base
  URL), as Better Auth already does, so the display page's mutations pass
  the origin check without operators listing it.
- Doctor validates EKKLESIA_DASHBOARD_ORIGIN exactly as the API's startup
  does (it previously skipped it), reports the topology without printing
  hostnames, and warns when split hostnames are not siblings.
- The module UI contract states the CORS header limit (safelisted headers
  plus Content-Type, safelisted response headers only).
- Reference deployment: Caddyfile.split.example (Dashboard hostname serves
  / and its script; API hostname serves /api/*, /display/*, and the
  display script; each refuses the other's paths) and
  EKKLESIA_DASHBOARD_HOSTNAME in the proxy overlay and env examples.
- The deploy smoke test runs either topology (CI runs both). The split run
  installs the module template as a test-only module, checks per-hostname
  routing and exact CORS, then drives a digest-pinned headless Chromium
  over the DevTools protocol, with no added dependency: sign-in on the
  Dashboard hostname, the session cookie host-only on the API hostname,
  the module UI imported cross-origin and its credentialed request
  succeeding, the display and its service worker on the API hostname, and
  sign-out.

ADR 0045 is marked Accepted.
