# Wipe the on-disk caches that the `cache` compose profile populates:
# the rpardini/docker-registry-proxy mirror + MITM CA, and the
# Sonatype Nexus 3 OSS data dir. Both live under /var/cache/infinito/
# core/<service>/ by default; the per-cache env scripts under
# scripts/meta/env/cache/ are sourced first so a custom HOST_PATH
# from the developer's environment is honoured.
#
# Removing the directories is enough: docker compose recreates them
# on the next `up` thanks to `bind: { create_host_path: true }`. For
# the Nexus side, the next bootstrap rotates a fresh admin password
# and re-creates blobstore + proxy repos.
#
# Use `make clean-cache` rather than calling this script directly.
