# Was nginx:alpine. The leaderboard needs one process that can WRITE, and nginx is not one.
# Everything the nginx conf was doing here — no-cache so a deploy is picked up on a plain reload,
# and a real MIME type for the manifest, without which Chrome refuses to install the homescreen
# app — is a few lines in server.py. Standard library only: no pip, no requirements file.
# ponytail: switch to hashed filenames if traffic ever matters.

# container's writable layer and every deploy silently resets the leaderboard to empty — which
# looks exactly like the feature working until the first time you push.
