#
#   owner         registry owner (user or org), default: heavy-duty
#   distribution  APT distribution, default: stable
#   component     APT component, default: main
#
# Authentication (first match wins):
#   1. STOKE_TOKEN environment variable (set from secrets.RELEASE_TOKEN in CI)
#   2. The token stored by `stoke auth login`
#
# The Forgejo URL defaults to the instance in the stoke config, falling back
# to https://forgejo.heavyduty.builders. Override with FORGE_URL.
