# Remove containers + images for challenges that are no longer enabled.
#
# Why: the platform can host 28 challenges but the images are large (1.2 GB for
# pasta alone) and the host disk is 79 GB. Keeping every image resident filled
# it to 98% and started failing builds. Disabled challenges keep their source in
# services/ and can be re-enabled at any time — only the runtime artifacts go.
