# Release pipeline: every push to `release` builds signed installers for every platform and
# creates or updates the draft GitHub Release "WordCraft v<version>". See docs/releasing.md.
#
# The signing jobs (macOS, Windows) and the job that drafts the release run in the `release`
# environment (restricted to the `release` branch), which holds the signing secrets. Every secret
# is optional: missing ones produce unsigned artifacts and a warning, never a failed build. The
# jobs that sign nothing (version, Linux, Flatpak, FreeBSD, web) get no environment and no
# secrets, so a `workflow_dispatch` on any branch dry-runs them; there the signing jobs are refused
# by the environment's branch rule, and the release job, which needs them, is skipped.
