/* ── iOS Glass UI Card Treatment ─────────────────────────── */

 * Authentic iOS-style liquid glass:
 * - Very low-opacity white fill (not dark tint) so the background

 * - Heavy blur (24px) + high saturation (180%) for true frosted-glass
 * - Hairline white border at full perimeter (iOS standard)
 * - Prismatic top-edge shimmer via a linear-gradient inset
 * - Layered shadows: ambient depth + sharp near-drop
