   SENSEIORA — LANDING PAGE (chế độ FULL-PAGE / trình chiếu)
   ---------------------------------------------------------------------
   Mỗi <section class="panel"> = 1 màn hình.
   Cuộn/lướt 1 lần -> nhảy gọn sang section kế (xử lý trong JS phần "FULLPAGE").
   - Đổi tông cả trang: sửa trong :root.
   - Đổi điều hướng/tốc độ chuyển: xem hằng số COOLDOWN / SWIPE trong JS.
   - Mobile (<=900px): tự chuyển về cuộn thường + chấm theo dõi (không "khoá" lướt).
