### If a host port is already taken

The mock services publish fixed host ports, and the suite fails at startup if
one is in use by something else on your machine:

```
Error response from daemon: Ports are not available: exposing port TCP
0.0.0.0:4100 -> 0.0.0.0:0: listen tcp 0.0.0.0:4100: bind: address already in use
```

Override just that one — the defaults are unchanged, and nothing inside the
stack is affected because services reach each other over the compose network
(`http://sms-sink:4100`), not via the host:

```bash
SMS_SINK_HOST_PORT=4102 make e2e-playground
```

| Variable | Default | Service |
| --- | --- | --- |
| `MOCK_OAUTH_HOST_PORT` | 4000 | mock-oauth |
| `MOCK_SAML_IDP_HOST_PORT` | 4001 | mock-saml-idp |
| `SMS_SINK_HOST_PORT` | 4100 | sms-sink |
| `WEBHOOK_SINK_HOST_PORT` | 4200 | webhook-sink |
| `CIMD_CLIENT_HOST_PORT` | 4300 | cimd-client |

This builds and starts the full docker-compose stack (six `authorizer` instances configured for different scenarios, the mock OAuth/SAML/SMS/webhook servers, Mailpit for email), runs the entire Playwright suite in a containerized runner, and **always** tears the stack down afterward (`docker compose down -v`) — including on failure or if the stack fails to start.

Equivalent to, run manually:
