#
# Runway Android RC Workflow
#
# Triggered from Runway to either:
# - Push an OTA update (when OTA_VERSION in app/constants/ota.ts line 9 is bumped), or
# - Build the mobile app (when there is no OTA version bump).
#
# When triggering workflow_dispatch, select the release branch (e.g. release/7.71.0).
