# Provide a local username + home for tools that call getpass.getuser() /
# os.path.expanduser() under arbitrary PUIDs. With `user: "1001:1001"` the
# stock python:3.13-slim image has no /etc/passwd entry for that UID, so
# pwd.getpwuid() raises and breaks libraries that do host-level user lookups
# (notably asyncssh, which uses the local username for ~/.ssh/config host
# matching during the SpoolBuddy remote-update flow). Setting LOGNAME/USER
# makes getpass.getuser() resolve via env vars instead of the passwd db;
# HOME=/app gives a writable home that is guaranteed to exist.
