#!/usr/bin/env bash
# Build, sign, notarize and package OpenCADStudio.app + .dmg for macOS arm64.
#
# Mirrors the `build-macos` job in .github/workflows/release.yml, then goes
# further: instead of the CI's ad-hoc signature it produces a Developer ID
# signed, hardened-runtime, notarized and stapled bundle. Ad-hoc signing is
# what breaks the QuickLook thumbnail extension and "Open with" registration
# in the field (#365): appexes must be sandboxed *and* validly signed before
# macOS will run them.
#
# Inputs (environment):
#   DEVELOPER_ID    "Developer ID Application: ..." identity. Auto-derived
#                   from the keychain when unset. Set to "-" for an ad-hoc
#                   build (CI parity, no notarization).
#   NOTARY_PROFILE  notarytool keychain profile. Unset → skip notarization.
#   VERSION         Bundle version. Default: version from Cargo.toml.
#
# Output: dist/OpenCADStudio.app and dist/OpenCADStudio-v<VERSION>-macos-arm64.dmg
