# Package the release binary into dist/tty7.app and wrap it in a
# drag-to-Applications DMG: dist/tty7-<version>-macos-<arch>.dmg.
#
# Signing posture is chosen from the environment:
#   * Developer ID secrets present (APPLE_SIGNING_IDENTITY + APPLE_CERTIFICATE)
#     -> hardened-runtime signature, then notarize + staple. Passes Gatekeeper.
#   * Otherwise -> adhoc signature, same as before. Fine for local dev, but the
#     OS will quarantine it on other machines.
