# Build the kiosk binary for multiple targets on tag push (vX.Y.Z), upload
# each as a GitHub Release asset, and optionally auto-import into a running
# BetterFrame server via /api/admin/firmware/import.
#
# Build environment is debian:bookworm-slim (matches Raspberry Pi OS Bookworm
# the kiosk deploys to). Building on Ubuntu would link against a newer glibc
# than the Pi ships → `GLIBC_2.38 not found` at runtime. Runner host distro
# doesn't matter; we run all steps inside the bookworm container.
#
# Required secrets:
#   BF_AUTOIMPORT_URL       e.g. https://bf.example.com  (optional)
#   BF_AUTOIMPORT_API_KEY   admin-scope API key for the BF server (optional)
