# cimery — Release build workflow (Sprint 23: Tauri v2 bundle)
# Triggered by pushing a version tag: git tag v0.1.0 && git push --tags
#
# Produces:
#   - Windows x64: .msi (WiX) + .exe (NSIS) + cimery-viewer.exe
#   - macOS arm64: .dmg + .app + cimery-viewer
#   - Linux x64:   .deb + .AppImage + cimery-viewer
#
# Sidecar: cimery-viewer is built first, then bundled alongside cimery-app.
# Code signing: placeholder (Azure Trusted Signing — ADR-003 A3).
