Thumbnail responses are immutable for a month, so nginx can answer repeats
from disk and never wake the web player or Google for them. The cache lives in
its own volume, collapses concurrent misses with a lock and serves stale
copies while it refreshes; THUMBNAIL_CACHE_SIZE sizes it.
ikerdemo.cat was hardcoded in six server blocks, so the stack could only be
deployed under that one domain. The vhosts are now a template rendered by the
nginx entrypoint from MUSIFY_ROOT_DOMAIN, with the envsubst filter set so it
does not eat nginx's own variables. The repeated proxy headers move to a
shared snippet, the web player vhost gets the upload body limit it was missing
(audio is posted to its form actions), and the streaming vhost turns off proxy
buffering so range requests stay responsive.
Matches the folder rename: compose service frontend -> web-player,
container musify-frontend -> musify-web-player, and the nginx upstream
now points at http://web-player:3000.
Deploying this needs --remove-orphans, or the old musify-frontend
container is left behind.
Compose file for ikerdemo.cat with nginx as TLS terminator, the three
.NET services, Zitadel and the storage stack. Values come from
deploy/.env.prod (untracked). Adds the frontend image, the migration
script and the Zitadel provisioning for production.
