# Until this existed the repo had no workflow with a `pull_request` trigger at
# all — only a tag-driven release — so Dependabot bumps arrived with no status
# check to gate a merge on and simply accumulated.
#
# macOS only, and deliberately. The CMakeLists branches on APPLE and WIN32 and
# has no Linux path at all, so ubuntu is not an option; Windows needs GLEW from
# vcpkg, which is a slow, fragile thing to put in front of every pull request
# for a compile break that would almost certainly show up on macOS too. The
# release workflow still builds both.
