# Image version (only used by docker-compose.images.yaml — the pull-based stack)

# Which published image tag to pull for api/dashboard/jobs.
#   - "latest" (below) = freshest main build; it MOVES on every merge to main (rolling, may
#     include unreleased code), so a later `pull` can shift you to a newer build unannounced.
#   - For production, PIN an exact release (e.g. 1.4.2) so a merge to main never auto-breaks you.
#     "1.4.2" / "1.4" / "1" are immutable, published on a v* git tag.
# Rollback = set this back to the previous version, then `... pull && up -d`.
