/**
 * BoxBMS Customer Rating Site - CSS Styles
 * 
 * ⚠️ ULTRA-MINIMAL COLOR SYSTEM
 * 
 * Để thay đổi màu giao diện:
 * 1. Đổi màu chính trong Settings của BoxBMS
 * 2. Rating site sẽ tự lấy qua /api/customer-rating/theme
 * 3. PRIMARY_COLOR/SECONDARY_COLOR trong config.php chỉ là fallback khi API lỗi
 * 
 * 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.
