/**
 * BoxBMS Customer Booking Site - CSS Styles
 * 
 * ⚠️ ULTRA-MINIMAL COLOR SYSTEM
 * 
 * Để thay đổi màu giao diện:
 * 1. Mở file public/booking/config.php
 * 2. Chỉnh sửa PRIMARY_COLOR và SECONDARY_COLOR
 * 3. XONG! Không cần động đến CSS này nữa
 * 
 * Hệ thống màu cực kỳ đơn giản:
 * - Chỉ 2 màu theme (primary, secondary) + 1 RGB variant
 * - Backgrounds, borders, shadows dùng rgba() với opacity
 * - Không có tên màu "pink", "yellow" - hoàn toàn neutral
 * - Works với BẤT KỲ màu nào: xanh, đỏ, vàng, tím, cam, etc.
