CLAUDE: Add multi-domain environment configuration support

- Create frontend-sba/.env.example and frontend-pd/.env.example templates - Fix hardcoded allowedHosts in nuxt.config.ts (now reads NUXT_ALLOWED_HOSTS) - Add NUXT_ALLOWED_HOSTS support to frontend-pd/nuxt.config.ts - Update docker-compose.yml with missing env vars: - FRONTEND_URL, DISCORD_SERVER_REDIRECT_URI - ALLOWED_DISCORD_IDS, WS_HEARTBEAT_INTERVAL, WS_CONNECTION_TIMEOUT - NUXT_ALLOWED_HOSTS for both frontends - Create docker-compose.prod.yml for production overrides - Update root .env.example with new variables - Add "Multi-Domain Deployment" section to README.md with checklist - Update all CLAUDE.md files with environment configuration docs - Remove obsolete 'version' attribute from docker-compose files 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

+## Environment Configuration
+
+### Multi-Domain Support
+The project is fully environment-driven for deployment to different domains. All URLs and credentials are externalized.
+
+### Environment Files
+| File | Purpose |
+|------|---------|
+| `.env.example` | Root template - copy to `.env` |
+| `backend/.env.example` | Backend-specific template |
+| `frontend-sba/.env.example` | SBA frontend template |
+| `frontend-pd/.env.example` | PD frontend template |
+
+### Key Environment Variables
+
+**Backend** (in `backend/.env`):
+- `DATABASE_URL` - PostgreSQL connection string
+- `DISCORD_CLIENT_ID/SECRET` - OAuth credentials
+- `DISCORD_SERVER_REDIRECT_URI` - Server-side OAuth callback
+- `FRONTEND_URL` - Frontend base URL for redirects
+- `CORS_ORIGINS` - Allowed origins (comma-separated)
+- `ALLOWED_DISCORD_IDS` - User whitelist (comma-separated, empty = all)
+
+**Frontend** (in `frontend-*/env`):
+- `NUXT_PUBLIC_API_URL` - Backend API URL
+- `NUXT_PUBLIC_WS_URL` - WebSocket URL
+- `NUXT_PUBLIC_DISCORD_CLIENT_ID` - OAuth client ID (public)
+- `NUXT_PUBLIC_DISCORD_REDIRECT_URI` - OAuth callback URL
+- `NUXT_ALLOWED_HOSTS` - Vite dev server allowed hosts (comma-separated)
+
+### Docker Deployment
+```bash
+# Development
+docker compose up
+
+# Production
+docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d
+```
+
+See `README.md` "Multi-Domain Deployment" section for full checklist.

+## Multi-Domain Deployment
+
+This project supports deployment to multiple domains. Key environment variables to configure:
+
+### Backend Variables
+| Variable | Description | Example |
+|----------|-------------|---------|
+| `FRONTEND_URL` | Frontend base URL for OAuth redirects | `https://yourdomain.com` |
+| `DISCORD_REDIRECT_URI` | Legacy Discord callback | `https://yourdomain.com/auth/callback` |
+| `DISCORD_SERVER_REDIRECT_URI` | Server-side Discord callback | `https://yourdomain.com/api/auth/discord/callback/server` |
+| `CORS_ORIGINS` | Allowed CORS origins (comma-separated) | `https://yourdomain.com,https://api.yourdomain.com` |
+| `ALLOWED_DISCORD_IDS` | Whitelist of Discord user IDs | `123456,789012` or empty for all |
+
+### Frontend Variables
+| Variable | Description | Example |
+|----------|-------------|---------|
+| `NUXT_PUBLIC_API_URL` | Backend API base URL | `https://yourdomain.com` |
+| `NUXT_PUBLIC_WS_URL` | WebSocket base URL | `https://yourdomain.com` |
+| `NUXT_PUBLIC_DISCORD_REDIRECT_URI` | OAuth callback URL | `https://yourdomain.com/auth/callback` |
+| `NUXT_ALLOWED_HOSTS` | Vite dev server allowed hosts (comma-separated) | `yourdomain.com,localhost` |
+
+### Production Deployment
+
+```bash
+# Using Docker Compose with production overrides
+docker-compose -f docker-compose.yml -f docker-compose.prod.yml up -d
+```
+
+### Domain Deployment Checklist
+
+When deploying to a new domain:
+1. [ ] Update Discord OAuth redirect URIs in [Discord Developer Portal](https://discord.com/developers/applications)
+2. [ ] Copy `.env.example` files to `.env` and configure all URLs
+3. [ ] Update `CORS_ORIGINS` to include new domain
+4. [ ] Add domain to `NUXT_ALLOWED_HOSTS` (if using dev server externally)
+5. [ ] Configure reverse proxy (Nginx/NPM) to route traffic
+
