 * Two surfaces:
 *   Desktop (≥901px): right-side drawer — slides in from the right (RTL start).
 *   Mobile (≤900px) : bottom sheet     — slides up from the bottom.
 *
 * Uses window.RHSheet (bottom-sheet.js) which calls showModal() on desktop
 * and show() on mobile so the <dialog> positions correctly in both contexts.
