# Build + publish the media-box container image to the GitHub Container Registry.
#
# Publishes linux/amd64 (Unraid's arch) so the image runs natively there — a bare
# `docker build` on an Apple-Silicon Mac produces an arm64 image that fails on
# amd64 Unraid with "exec format error". better-sqlite3 + sharp compile per-arch,
# so building for the target arch is what makes them load correctly.
#
# Auth: no manual secret needed. The job's built-in GITHUB_TOKEN pushes to
# ghcr.io/devblaze/media-box thanks to `permissions: packages: write` below.
#
# NOTE: after the first successful run, the ghcr package defaults to PRIVATE.
# Make it public (github.com/users/devblaze/packages/container/media-box/settings
# → Change visibility → Public) so Unraid can pull it without a docker login.
