/* =========================================================
   Footer Modern V1.9 — reference-exact + balanced short page
   Mục tiêu:
   - Bố cục/nhịp gần footer tham khảo Tailwind: pt-12, gap-8, mb-12, pt-8/pb-8.
   - Không body flex, không margin-top:auto, không sticky/fixed footer.
   - Trang dài: footer có chiều cao tự nhiên.
   - Trang ngắn desktop: phần chiều cao thiếu được phân bổ cân đối trong footer,
     tránh một dải trắng lớn chỉ nằm trên hoặc dưới.
