/* Device Frame — iPhone 15 Pro (to-scale CSS mockup)
 * Usage: Wrap mobile UI in <div class="device-frame"><div class="device-screen">...</div></div>
 * On desktop: shows a realistic phone bezel with scrollable content
 * On mobile (<768px): frame disappears, raw UI fills the viewport
 *
 * iPhone 15 Pro viewport: 393 × 852 CSS px
 * Device shell adds bezel, dynamic island, side buttons
