Appearance
Dark Mode for Mac notch developers
If you are extending NotNotch, Dark Mode is a host surface or a documented constraint. The companion follows system light and dark appearance.

Host rules
Packages declare placements in manifest.json. Dark Mode may be openTab, liveActivity, or a first-party module.
Do not disable library validation
Unsigned third-party binaries stay manifest-only. That is intentional.
