# Two jobs:
# - validate: builds the Dockerfile on PRs only. Fast, no GHCR push. On push to
#   main, publish builds the same image, so a separate validate build would just
#   duplicate it (and double the disk pressure on the runner).
# - publish: runs only on main + version-tag pushes. The bake artefacts
#   (`data/pages/`, `qdrant_local/`) are committed to git, so this job is
#   just `docker build` + `docker push`. ~10-15 min cold cache, ~3 min warm.
#
# Why the artefacts are committed: the CPU bge-m3 embed loop on a free
# GH runner takes ~100 min for the curated 20-paper corpus, blowing past
# any reasonable timeout. ~110 MB of binary artefacts in git history
# trades repo size for deploy reliability.
