1//! Touch-side support types for the CYD's `cyd` device abstraction.
2//!
3//! Apps read calibrated screen-space events via [`TouchEvent`]. Devices also
4//! implement [`super::CydTouchUncalibrated`] so the shared touch-calibration
5//! flow in [`calibration`] can read raw controller samples and transition
6//! into a calibrated [`super::CydTouch`].
