# Builds both architectures, publishes the two installable component packages as
# workflow artifacts, and — when a tag is pushed — turns them into a GitHub release.
# The SDK is fetched from foobar2000.org at build time (tools/setup_sdk.ps1) and the
# renderer sources are part of this repository (kernel/), so nothing else is needed.
