Tips & operations
- Postgres for production — SQLite ok for small / personal
- Session secret in env — sign-in tokens; protect this
- OAuth setup — needed for team workflows
- Free URL mode — allow custom slugs (security trade-off, careful)
- Backup Postgres + uploads — both essential
- HTTPS production — required for Service Worker features
