name: Refresh map geometry

# Regenerate the committed SVG map geometry the web app colors at runtime:
# web/us-states.json, web/world-countries.json, and web/subdivisions/<cc>.json.
# The three build scripts re-download public-domain source boundaries (Natural
# Earth admin-0/admin-1, PublicaMundi US states), re-project them, and rewrite
# the simplified paths.
#
# This is deliberately dispatch-only: it never runs on the daily cron or on
# push, so it cannot disturb the daily Pages deploy. Trigger it from the Actions
# tab to pull in a Natural Earth update or after new countries gain cohort
# depth, and it opens a pull request only when the geometry actually changed.
# Run the same scripts locally with `make map-geometry`. See docs/visualization.md.
