//! Touch-side support types for the CYD's `cyd` device abstraction.
//!
//! Apps read calibrated screen-space events via [`TouchEvent`]. Devices also
//! implement [`super::CydTouchUncalibrated`] so the shared touch-calibration
//! flow in [`calibration`] can read raw controller samples and transition
//! into a calibrated [`super::CydTouch`].
