On-device extensions on a Mac
extensions is implemented in the native Swift app, not as a web view in the notch. Settings can install .boringnotch packages; unsigned binaries stay manifest-only.

Why native matters
A real Mac utility can follow Spaces, displays, and system appearance. extensions is part of that host.
What stays in-tree
First-party extensions lives in the app. Third-party packages cannot load unsigned code.
