/* Tutorial System Styles
 *
 * Flat z-index structure (all elements are siblings in DOM):
 * - Backdrop: z-index: 100000 (dark overlay, blocks clicks)
 * - Spotlight: z-index: 100000 (visual only, no pointer events)
 * - Highlighted Element: z-index: 100001 (clickable, above backdrop)
 * - Tooltip: z-index: 100002 (always on top, clickable)
 *
 * Note: High values needed because desktop/windows use z-index 9999-10000+
