 * ===== CSS SPECIFICITY REFACTORING COMPLETED =====
 * 
 * SOLUTION: Loại bỏ !important bằng cách tăng CSS specificity tự nhiên
 * 
 * HIERARCHY MỚI:
 * 1. Desktop hover: .tikz-app:not(.mobile-device) .file-card:not(.menu-open):hover .file-action-container
 *    Specificity: (0,0,5,0) = 50
 * 
 * 2. Mobile menu-open: .tikz-app.mobile-device .file-card.menu-open .file-action-container  
 *    Specificity: (0,0,5,0) = 50 (same as desktop, but cascade order wins)
 * 
 * 3. Mobile buttons: .tikz-app.mobile-device .file-card.menu-open .file-action-container .Btn.individual-active
 *    Specificity: (0,0,6,0) = 60 > Desktop (50) ✅ WINS WITHOUT !important
 * 
 * KẾT QUẢ: ZERO !important declarations needed ✅
 * 
 * JAVASCRIPT INTEGRATION COMPLETED:
 * 1. Device Detection: ✅ Add 'mobile-device' class to .tikz-app when on mobile
 * 2. Menu State: ✅ Add 'menu-open' class to .file-card when action menu is opened
 * 3. Removed legacy: ✅ Replaced 'is-touch' and 'active' class logic
 * 
 * Example JavaScript Integration:
 * document.querySelector('.tikz-app').classList.add('mobile-device');
 * fileCard.classList.add('menu-open');
