   SERVICE-CUSTOM.CSS - SECTION DỊCH VỤ VÀ ĐIỀU TRỊ NHA KHOA 3D
   Tuân thủ nghiêm ngặt 4 nguyên tắc:
   1. Kế thừa & cải tiến có chủ đích: Giữ nguyên bố cục 2 cột (Lưới dịch vụ bên trái + Ảnh xem trước bên phải)
   2. Phong cách thực tế, không "AI":
      - Không kính mờ (glassmorphism), không đèn neon/pulse, không dải gradient viễn tưởng
      - Nền trắng/xám trung tính sạch sẽ, viền mảnh 1px tinh tế (#e2e8f0), đổ bóng mềm tự nhiên
      - Font chữ sans-serif hiện đại, nét đứng, chuẩn tiếng Việt
   3. Kỹ thuật Responsive & Chống vỡ layout:
      - Co giãn linh hoạt (grid, flex), không px cứng gây tràn
      - Vùng chạm (touch) tối thiểu 44x44px trên mobile
   4. Thử nghiệm ổn định chữ tiếng Việt rớt 2-3 dòng
