| `docker-compose.yml` | Full-stack orchestration using `expose: "3000"` (eliminates `Bind for 0.0.0.0:3000 failed` host port conflicts). |
| `.dockerignore` | Context exclusions for slim Docker image builds. |
| `.env.example` | Template environment variables (`DATABASE_URL`, `PORT`, `DATA_PATH`, `SMTP_*`). |
| `COOLIFY.md` | Deployment & port binding troubleshooting guide for Coolify platform & Traefik proxies. |
| `server.ts` | Express server entry point with PostgreSQL initialization, environment SMTP dispatching, and REST API routes. |

## 🛠️ Local Development & Running via Docker

### 1. Run via Docker Compose
```bash
docker-compose up --build -d
```
The application container exposes port `3000` via Docker's internal network (`expose: "3000"`), avoiding host interface port allocation collisions.

### 2. Run via Docker CLI
```bash
docker build -t balance-sheet-portal .
docker run -p 7000:3000 -v portal_data:/app/data balance-sheet-portal
```
