# Gitea Actions: Docker Build, Push, and Notify
#
# CI/CD pipeline for Paper Dynasty Database API:
# - Triggered by pushing a CalVer tag (e.g., 2026.3.11) or "dev" tag
# - CalVer tags push with version + "production" Docker tags
# - "dev" tag pushes with "dev" Docker tag for the dev environment
# - Sends Discord notifications on success/failure
#
# To release: git tag 2026.3.11 && git push origin 2026.3.11
# To deploy dev: git tag -f dev && git push origin dev --force
