# CI workflow for the map rendering crate.
#
# Enforces:
#   1. The map crate compiles (lib + tests).
#   2. The test suite is green.
#   3. No regressions in tile parsing, style compilation, or tessellation.
#
# This workflow was added to catch runtime errors like:
#   - 'too many elements (N > 100000)' from overpass_parser
#   - 'type mismatch for property style_light: expected MapThemeStyle'
#   - triangulation failures in tile_disk
