Every Weblate container (weblate, beat, worker) runs collectstatic into
STATIC_ROOT=/app/cache/static on start. /app/cache is the `cache` volume
the three services share; in swarm it lives on NFS and every replica of
every service mounts the same directory. Concurrent collectstatic runs
delete and rewrite each other's hashed files, so the tasks crash-loop:
weblate.1, .2, .3 and worker.1 on both swarm nodes died with
"FileNotFoundError: [Errno 2] No such file or directory:
'/app/cache/static/admin/js/vendor/select2/i18n/az.270c257daf81.js'"
(and logo-32.png, dark_mode.a364bd93cdcc.css, widgets.8f8bf7f533a4.js),
which failed Weblate#1 in runs 40625679270 and 40243434327.
meta/volumes.yml mounts a tmpfs at /app/cache/static into every service
that shares the cache volume, so each container collects and serves its
own copy, consistent with its own manifest; the rest of /app/cache stays
shared. container_volumes renders it as a long-form tmpfs mount for
compose and swarm alike, as it already does for the Matrix bridges.
test_static_root_per_container asserts that every service mounting the
shared cache also gets the tmpfs at the static root.
