# Post-process the Flutter macOS Release bundle so it actually launches:
#
#   1. Wrap target/release/libchanora_bridge.dylib into a proper
#      chanora_bridge.framework bundle (Versions/A layout, Info.plist,
#      symlinks). FRB on macOS dlopen()s chanora_bridge.framework/
#      chanora_bridge — not the plain dylib.
#   2. Rewrite the dylib's LC_ID_DYLIB so dyld resolves it as
#      @rpath/chanora_bridge.framework/chanora_bridge.
#   3. Ad-hoc codesign the framework + the .app bundle.
#
# This is the macOS analogue of buildit.cmd on Windows. cocogkit /
# corrosion-style auto-integration into the Xcode project is a P1
# carryover — for now we run this script after `flutter build macos
# --release`.
#
# Usage:
#   tools/macos-postbuild.sh [Release|Debug]   (defaults to Release)
