# The Android client this server hands out. CI fetches the newest published build
# into ./client immediately before this runs (ci.yml), so every image tag — :dev,
# :latest and :<version> alike — ships a client, and a `docker compose pull`
# delivers a new one with no file copying by hand.
#
# Fetched by the JOB rather than here on purpose: the release is private, and a
# token used inside a build ends up in the build context or a layer.
#
# The directory is tracked (client/.keep) so this COPY cannot fail on a tree where
# that step never ran. An image with no APK is a supported state — the server
# advertises nothing and the web UI hides the download (client_dist.py).
