-**Conventions**
-
-* Branching model: `main` (stable), `develop`, feature branches `feature/*`.
-* PRs require reviews & passing checks.
-* Issues labeled with `area/backend`, `area/web`, `area/mobile`, `good-first-issue`.
 
-> If you change folder names or ports, reflect them in `docker-compose.yml` and `.env*` files. This README targets a **fresh programmer** who knows general tools but not your project or Docker; it is safe to follow step‑by‑step.
