automatically. If no files are found in `/music`, the built in tracks located in automatically. If no files are found in `/music`, the built in tracks located in
`/music/default/` will be used instead. `/music/default/` will be used instead.
The nginx configuration also sets the `X-Weatherstar: true` header on all
responses. This uses `add_header ... always` so the header is sent even for
404 responses. When `playlist.json` returns a 404 with this header present, the
browser falls back to scanning the `/music` directory. If you host the static
files elsewhere, be sure to include this header so the playlist can be generated
automatically.
