# Release builds: push a tag `v*` (or run it by hand with a tag name) and this builds the desktop
# app and the CLI for Linux, Windows and macOS plus the web app, and attaches them to a GitHub
# release with SHA256SUMS (a pre-release when the tag has a suffix, such as v0.2.0-rc1). Every
# download is a plain program (Windows .exe, Linux binary and AppImage, a macOS .dmg); the licences
# are built into the programs (Help ▸ About ▸ Licences, `solvecraft-cli licences`). Only the web
# app, being many files, is a zip. Notes: .github/release-notes.md, with {tag} replaced. A dry run:
# Actions ▸ Release ▸ Run workflow with "publish" off keeps the assets as the release-assets artifact.
