/**
 * ZOOM UI EXCLUSION TEST
 * =======================
 * Verifies that UI elements (footer, menu, buttons) are NOT affected by zoom
 *
 * Test Requirements:
 * - Footer should NOT be inside #zoom-wrapper
 * - Action bar should NOT be inside #zoom-wrapper
 * - Hamburger menu should NOT be inside #zoom-wrapper
 * - Fixed buttons should NOT be inside #zoom-wrapper
 * - Only .cv-container content should be affected by zoom
 *
 * Test Flow:
 * 1. Load page and show zoom control
 * 2. Measure initial sizes of UI elements
 * 3. Set zoom to 200%
 * 4. Verify UI elements remain same size
 * 5. Verify CV content has doubled in size
