# Usage: scripts/build-release.sh TAG OUTDIR
#        scripts/build-release.sh v0.1.0 dist
#
# CI runs exactly this on a v* tag (.gitea/workflows/release.yml), so a
# release can be built and checked on any machine with Go before tagging.
#
# Static (CGO off), so each binary runs anywhere its OS and architecture do.
# The editor's interface is embedded from internal/editor/ui/dist, which is
# committed and checked against its source on every pull request. The tag is
# stamped in, so `hotdog-cms version` and the release can't disagree.
