 ### Changed
 
+- **Coolify host-port de-collision**: Published playout on host port `8081` (`${PLAYOUT_PORT:-8081}:8081`) and moved the nginx host port from `8080`/`80` to a free `8082` (`${NGINX_PORT:-8082}:80`) in both `docker-compose.yml` and `docker-compose.prod.yml`, so no service binds ports reserved by the Coolify environment (Traefik proxy `80`/`443`, dashboard/Portainer `8000`, and the taken `8080`). `NGINX_PORT` default in `.env.example` updated from `80` to `8082`.
+
 - **Docs condensed and de-Windows'd**: Removed Windows/PowerShell-specific instructions from the docs and condensed the longest documents into tighter, bash-first guides — `SETUP.md`, `DEPLOYMENT.md`, `API.md`, `MONITORING.md`, `STREAMING.md`, `COOLIFY.md`, `incident-runbook.md`, `operations/scaling-performance-playbook.md`, `architecture/README.md`, and the Prometheus metrics inventory. `scripts/loadtest/README.md` now documents the bash load-test helpers.
 - **System messages no longer persisted**: The chat backend no longer stores `system`-type messages; chat history and the admin chat-log table only contain real chat messages (moderation actions remain in the audit log).
 - **Reconnect grace period**: Disconnects schedule a delayed "left" announcement (5s); a reconnect within 5s cancels it and skips "joined", eliminating join/leave spam on brief reconnects.
