Implements the security core of the plugin system: code-plugin surfaces
run in opaque-origin iframes (sandbox="allow-scripts", never
allow-same-origin) with a capability-filtered RPC bridge.

- api: serve a per-plugin sandbox frame document at
  /plugins/:id/:version/frame with a CSP that pins every load to the
  plugin's own asset path (built from APP_BASE_URL, not the request Host,
  so a Host-rewriting proxy cannot break it) and forbids network access
  (connect-src 'none'). Plugin assets get Access-Control-Allow-Origin: *
  so the null-origin frame can load its own module bundle.
- web: sandbox-host creates the frame, wires the SDK host bridge over a
  source-filtered postMessage transport, drives render under a 5 s
  deadline (hung/failed plugin -> placeholder, never a frozen page), and
  tears down on unmount. PluginFrame/PluginPreviewPage surface it; the
  built-in ui.resize handler clamps plugin-requested heights.
- plugin-sdk: host bridge reports gate violations via onViolation and
  registers a gated handler for every v1 method, so an undeclared
  capability is rejected with capability_not_permitted (not
  unknown_method).
- tests: SDK gate unit test; web sandbox unit tests (opaque origin,
  source filtering, timeout); and the e2e security pack with a permanent
  malicious fixture plugin proving no escape (DOM/cookies/storage/fetch/
  undeclared capability all blocked) plus well-behaved and hung cases.

f500198c5d Add per-pond fonts: catalog, build, application, and admin UI (#66)

Self-hosted Google Fonts with per-pond selection (ADR 0016), the GDPR
"zero external requests" posture (security.md, CSP `font-src 'self'`).

- Catalog: a curated 15-family OFL/Apache list in shared (family, weights,
  category, license, google-webfonts-helper id). `deploy/fonts/build-fonts.mjs`
  validates every entry has license info (fails the build otherwise),
  downloads the WOFF2 weights into apps/web/public/fonts/ (gitignored), and
  generates the @font-face stylesheet — run at image build time from the web
  Dockerfile (with retries), never from a visitor's browser.
- Application: PondFontScope sets --font-heading/body/mono (+ weights) from
  pond.settings.fonts on the editor + read view; the existing global CSS
  already reads those custom properties, so headings/body/code re-resolve to
  the pond's fonts. A pond with no settings arrives with the defaulted values
  (Roboto 400 / Roboto 200 / Fira Code), so the vision defaults always render.
- Admin UI: pond-settings 'Appearance' section — three slots (family + weight)
  with a live preview, Pond-Admin-gated (fonts added to updatePondInputSchema
  and merged in PondsService.update); a font catalog attribution page (/fonts)
  listing families and licenses. New `font` i18n namespace (de+en).
- CSP: strict Content-Security-Policy in nginx.conf (default-src 'self';
  font-src 'self'; style-src 'self' 'unsafe-inline'; script-src 'self'; …) —
  the app's scripts are all external files, inline styles cover CSS variables.
- Tests: shared catalog-integrity unit test (the invariant the build enforces);
  e2e fonts pack — no request leaves the origin when rendering a pond (the GDPR
  network assertion), a font choice applies to a page and persists, and a pond
  without settings renders the defaults.

6e5a632c31 Add production Dockerfiles and the Compose stack with dev overlay
Multi-stage images: web (workspace build baked into unprivileged
nginx with SPA fallback, asset caching, /healthz) and api (pnpm deploy
bundle with the prisma CLI for migrate-on-start, non-root, node-based
healthcheck). deploy/compose/docker-compose.yml defines the stage
stack (web, api, db) with frontend/internal networks, localhost-only
published ports for the host reverse proxy, log rotation, and named
volumes; .env.example documents every variable. compose.dev.yml layers
hot-reloading dev containers (or database-only usage) over the same
definition. Verified locally: full stack healthy, SPA fallback, readyz
green after automatic migration, db not reachable from outside.

Closes #6
