JakeBreath bd812bb601 Write video output to a real OPFS file instead of assembling chunks
The hand-rolled chunk assembly was verified correct in Node but still
produced a broken MP4 in the browser, so stop relying on it: the muxer now
streams into an Origin Private File System file (random access is exactly
what MP4 needs), the worker returns the OPFS File directly, and the entry
is deleted after a successful apply (stale ones are purged hourly). The
chunk collector remains only as a fallback for browsers without OPFS.

The result is validated before it reaches the UI: MP4s must contain a
moov box and WebM files must start with the EBML magic, so a broken muxer
output surfaces as an error instead of a 0x0 preview.

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.
