/**
 * MACOS DOCK-STYLE TOOLTIPS TEST
 * ================================
 * Tests macOS Dock-inspired tooltips for action buttons
 *
 * REQUIREMENTS:
 * - Tooltips appear on hover with smooth animation
 * - Desktop: tooltips on RIGHT side (vertical buttons)
 * - Mobile: tooltips on TOP (like macOS Dock)
 * - Back-to-top: tooltip on LEFT side
 * - Smooth fade + scale animation
 * - Dark semi-transparent background
 * - No tooltips on touch devices
 */
