/**
 * PinFieldHiddenInput is the single, visually hidden `<input>` that backs the PinField UI.
 *
 * It stores the full PIN value in one place while the visible pin “cells” render the
 * per-character representation. The input is hidden via `VisuallyHidden` but remains
 * focusable and accessible for keyboard input, screen readers, and browser autofill.
 *
 * The component is fully integrated with `usePinFieldContext()` and is responsible for:
 * - Synchronizing the active cell index based on caret/selection position (`syncActive`)
 * - Writing the current value into PinField state on input (`setValue`)
 * - Resetting the active cell on blur (`setActive(-1)`)
 * - Detecting “select all” state and reflecting it in PinField (`setSelectedAll`)
 *
 * Selection handling:
 * - Uses `onSelect` to determine whether the whole value is selected
 *   (start === 0 && end === value.length) and updates `selectedAll` state.
 *
 * Notes:
 * - `onInput` schedules `syncActive()` in `requestAnimationFrame` to ensure the DOM
 *   selection state is up to date before computing the next active index.
 * - External event handlers passed via props are merged with internal handlers.
