name: Docker image

# Builds + pushes ghcr.io/ariomoniri/syntha:<tag> on every v* tag, plus a
# rolling :latest. Also builds on push-to-main as :main so users can pin
# to a bleeding-edge image if they want.
#
# Multi-platform: linux/amd64 + linux/arm64. arm64 build is ~3× slower
# but covers Apple-Silicon Docker Desktop and AWS Graviton.
