trigger-deploy.yml

# Hosting for this game lives in the WesleyArcadeSite repo (it owns the single
# Firebase Hosting site behind wesleyarcade.com). Pushing here therefore has to
# poke that repo to rebuild and redeploy the arcade.
#
# Requires two repo secrets, APP_ID and APP_PRIVATE_KEY, for the same GitHub App
# ReflectionsPhaser uses, with the app installed on WesleyArcadeSite. Until those
# exist the job skips with a notice rather than failing -- a red run on every
# push emails the owner about a condition they already know about, and trains
# them to ignore the one failure that eventually matters.
#
# Without the secrets, deploy by hand:
#   gh workflow run "Deploy to Firebase Hosting" --repo TomWesley/WesleyArcadeSite
