JakeBreath a904abdf20 Run the SPA without a backend (local mode)
The app can now operate backend-agnostically: a production build still
asks on first start, but /setup also offers 'Continue without a backend'
(stored as the sentinel 'none'), and the shell adapts:

- Local mode shows only the e621-facing pages: Online (search, post view,
  favorites, blacklist editor, direct downloads) and Pools. Library,
  uploads, duplicates, stats, users, follows and similarity are hidden
  from the nav and palette and render a 'backend needed' state when
  reached directly; /detail/<e621 id> still works while /detail/J-x asks
  for a backend.
- e621 credentials are stored in this browser (j621.e621) and the
  Account page becomes a credentials-only screen; the store reads/writes
  locally instead of /api/auth/e621/.
- The header replaces the status pill and login/user area with an e621
  credentials button and a 'Setup Backend' button; the footer shows
  'Local mode — e621 features only' with the same entry point.
- In-library lookups (badges/browse markers) are skipped without a
  backend; 'Download to client' links straight to the e621 file instead
  of the backend proxy; follow buttons and palette follow toggles are
  hidden; api() fails fast with a clear message if something slips
  through.

Mode logic lives in lib/backend.ts (URL / '' same-origin / 'none') with
its matrix verified in Node; tsc, oxlint and the build are clean.

J621

Self-hosted media library and e621 archive manager, rebuilt as a React SPA + Django REST API.

Structure

backend/    Django 6 + DRF API (SQLite in dev, MariaDB in production)
frontend/   Vite + React + TypeScript SPA

Development

Backend

cd backend
source venv/bin/activate
python manage.py migrate
python manage.py scan_files            # index the watched folder
python manage.py runserver

Copy .env.example to .env and set WATCHED_FOLDER before scanning.

Frontend

cd frontend
npm install
npm run dev                            # http://localhost:5173, proxies /api to :8000

Production

Not wired up yet — planned: Nginx serving the SPA build, /media and /library media directly, and proxying /api to Waitress/Django. See frontend/ design docs for the UI specification.
