browser-device-orientation
Wraps DeviceOrientationEvent as global atoms, exposing the raw tilt snapshot plus alpha / beta / gamma and a compass-heading selector.
Permission
iOS requires a user gesture: call requestOrientationPermission() from a click handler before subscribing. Other browsers grant on subscribe.Install

Cross-framework
Global atoms/selectors — works in every framework, only the read primitive differs. The deviceorientation listener starts on the first subscriber and stops on the last.
