Minimal CarPlay sample that reproduces a hit-testing bug: an enabled CPButton in a
CPListTemplateDetailsHeader does not respond across its full visible area on iOS 27.
Only the upper part of the button fires its handler.

- Environment: Xcode 27.0 (27A266a), iOS 27.0, CarPlay Simulator and a real CarPlay display
- Entitlement:

- Run on an iOS 27 iPhone with CarPlay connected, or use the CarPlay Simulator.
- In CarPlay, open the app and select Coastal Road Trip.
- Tap different parts of the Continue Trip button. A CarPlay alert appears when the handler fires.
- Select a day card and repeat with Next Stop.
Expected: the action fires from anywhere on the visible button. Actual: only part of the button responds.
The phone screen and the console also log each callback.
