A custom debounce hook supporting leading, trailing, and maxWait options. It maintains stable function references and provides a `cancel` method. This implementation is self-contained, handles edge cases (e.g., immediate leading call), and can be extracted into any React project needing precise debounce behavior without external dependencies.

A hook that distinguishes between single and double taps using a combination of a debounced callback and a click counter. It cancels the pending single tap on detection of a second tap. This pattern is reusable for any component needing tap gesture detection (e.g., image zoom, gallery navigation) and is decoupled from the photo preview logic.

Implements physics-based scroll deceleration, rebound animation, and easing functions. It calculates speed from touch movements, applies acceleration and resistance, and handles edge rebound using `requestAnimationFrame`. This complex animation logic is isolated in a single hook and can be reused in any touch-based scrollable component (e.g., carousel, image viewer, drag-to-dismiss).

A hook that creates a stable object of callback functions that always reference the latest closure. It uses a ref to hold the latest functions and returns a proxy object that delegates calls. This pattern solves the common React problem of passing stable callback references to child components without re-renders, and is entirely generic and reusable.

Computes new x/y positions when scaling an element around a touch point, handling edge cases like long mode images and edge offsets. It uses the formula for scaling around a point and adjusts for closed edges. This utility is self-contained and can be reused in any zoomable/pannable interface.
