 ## Architecture
 
 - **Routers**: Domain-based in `app/routers_v2/` (cards, players, teams, packs, stats, gauntlets, scouting)
-- **ORM**: Peewee with SQLite (`storage/pd_master.db`, WAL journaling)
+- **ORM**: Peewee with PostgreSQL
 - **Card images**: Playwright/Chromium renders HTML templates → screenshots (see `routers_v2/players.py`)
 - **Logging**: Rotating files in `logs/database/{date}.log`

 ### Common Issues
 - 502 Bad Gateway → API container crashed; check `docker logs pd_api`
 - Card image generation failures → Playwright/Chromium issue; check for missing dependencies
-- SQLite locking (dev) → WAL mode should prevent, but check for long-running writes
 - DB connection errors → verify `POSTGRES_HOST` points to correct container name
 - **CI/CD**: Gitea Actions on PR to `main` — builds Docker image, auto-generates CalVer version (`YYYY.MM.BUILD`) on merge
