Makes the behind-login features usable on the dev preview with no server and no credentials.

  • src/preview-demo/: a pure in-memory Matrix handler (server.ts, fixtures in fixtures.ts) behind a guarded fetch (install.ts). Own-origin requests pass, https://demo.invalid is answered in-page, every other origin is refused (fetch, WebSocket, XHR, beacon).
  • Built in only with VITE_PREVIEW_DEMO=1 and switched on by previewDemo: true in config.json (scripts/preview-config.js low --demo, run by the dev workflow). A build without the flag contains none of it (checked by grep).
  • Login prefills demo (any password); a banner says pretend server. First visit turns the pose-portraits setting on.
  • Fixtures: General (training line), Ratatoskr (study), Huginn (show), a DM with Eureka, an unjoined public room. Messages carry org.gamecult.pose; a Mind answers whatever you send.
  • Pose art: 24 downscaled thumbnails (preview-demo/poses, ~200 KB) copied into dist by the workflow; the full art stays unsynced.
  • Tests: the real matrix-js-sdk logs in, syncs, sends and joins against the handler; the guard refuses foreign origins.

Public-safe fixtures: only the Minds and a fictional visitor.

The host CSP sandbox lacks allow-forms; Chrome drops native submission before the submit
event fires, so the login button did nothing in a real browser (found driving Chrome).

Found driving Chrome: the pose setting was seeded after settings.ts had already read defaults;
the Connecting bar stayed until the first 15 s long poll returned.

Provenance note on the pose thumbnails in this PR.

The 24 PNGs under preview-demo/poses/ (about 200 KB in total, 160 px wide, palette-quantised) are downscaled copies of GameCult's own Persona art from /opt/commons/cast-art/poses. That directory carries no provenance or licence note: the image model that made the art and the terms it was made under are not recorded. I committed them so the dev preview can show pose portraits; the full-size art stays unsynced and uncommitted.

Meta may veto. If so, strip them: delete preview-demo/poses/ and the Add the demo pose art step in .github/workflows/rat-dev-preview.yml. The demo then runs with broken portrait images (everything else is unaffected).

A README with the same text is in the follow-up PR onto dev.
