name: Release

# Release is triggered by pushing a vX.Y.Z tag.
#
# PREREQUISITE: Before tagging, merge develop → main via PR.
# The tag must point to a commit on main, NOT develop.
# GitFlow: develop (default) → PR → main → tag → release.
#
# This workflow does NOT sync main — main must already be up to date.
