Rename stack service from backend to runners-calendar-backend so DNS on
shared external networks (e.g. postgres_default) cannot resolve to
another project’s backend. Nginx proxy_pass targets the same hostname.
Made-with: Cursor
- Remove PLAN/agent instruction files; single root .env.example for DB + API
- Stack compose uses env_file .env; delete stack env example duplicate
- Refresh README, backend docs, API doc; trim gitignore/dockerignore
Made-with: Cursor
- docker-compose.stack.env for DB_* and CORS (gitignored)
- docker-compose.stack.env.example with placeholders
- .dockerignore excludes local stack env from build context
