# Remove per-team duplicate challenge images and repoint every team compose at
# the shared `services-<name>` image.
#
# Why: before services-<name> images existed, enabling a challenge made each of
# the 4 teams build its own copy (team1-x, team2-x, ...). A challenge image is
# identical for all teams — the SSH password is applied at container start via
# chpasswd, never baked in — so one shared build is enough. Those duplicates
# were consuming ~1.5 GB on a disk that only has ~3 GB free.
