Extensions
On-device Hello demo extension on a Mac
Hello demo extension is implemented in the native Swift app, not as a web view in the notch. The first-party Hello plugin is off by default and can show a tab plus a host-drawn chip.

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