name: Release

# Builds Gridline installers for macOS (Apple Silicon + Intel), Windows, and
# Linux, then uploads them to a draft GitHub Release.
#
# Trigger: push a version tag from the `prod` branch (production), e.g.
#   git checkout prod && git pull
#   git tag v0.5.0 && git push origin v0.5.0
#
# SIGNING STATUS: builds are UNSIGNED for now (no code-signing certs yet —
# see README "Download a release"). tauri-action automatically signs +
# notarizes when the signing secrets are present, so the moment we add
# APPLE_CERTIFICATE / APPLE_API_KEY / WINDOWS_CERTIFICATE (or Azure Trusted
# Signing) to repo secrets, future builds are signed — no changes to this
# file required.
