 On SELinux hosts (Fedora, RHEL), compose mounts the checkout with `:z` so the container may read it; Docker may relabel the checkout for container access, which can take a moment on a large checkout. Without that, the start fails with `Cannot find module '/app/scripts/docker-start.mjs'`.

The map routes compare the browser's `Origin` with the `Host` the server sees, so the proxy must pass the original `Host` and, when it terminates TLS, `X-Forwarded-Proto`. Caddy does both by default; for nginx add `proxy_set_header Host $http_host;`, `proxy_set_header X-Forwarded-Proto $scheme;` and `proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;`. On an install outside Docker, that forwarding header also rate-limits the proxy's users apart from your own browser. Under the default Docker bridge network every client on the host, your browser included, reaches the container from its gateway address and shares one Overpass bucket.
