/**
 * Switch — binary on/off toggle atom (form-associated).
 *
 * Pattern B (atom-interactive, form-associated): renders its own
 * `<input type="checkbox" role="switch">` inside shadow DOM and paints the
 * visual track + thumb with CSS. Implements the WAI-ARIA switch pattern, not
 * the checkbox pattern — `role="switch"` with `aria-checked="true|false"`.
 * Space toggles per native checkbox semantics; the role swap does not break
 * keyboard activation.
 *
 * The visible track is 48 × 28px; the hit area expands to 32px on
 * pointer-devices and 40px on touch-devices (via `pointer: coarse`) per the
 * Figma "Target Sizes" spec, achieved with a `::before` pseudo-element so the
 * visual footprint stays untouched.
 *
 * @element mud-switch
 *
 * @slot label - Rich label content, replaces the `label` prop when present.
