/**
 * SOFT4U C1 — Single product redesign (CSS)
 *
 * Nguyên tắc:
 *   - Mọi class prefix `s4u-product-` / `s4u-cmp-`.
 *   - Rule layout "mạnh" scope dưới `.s4u-product-redesign` (body class)
 *     để không rò rỉ sang trang khác.
 *   - KHÔNG đổi màu/format khối giá (#custom-price-display, .price) —
 *     chỉ căn khoảng cách.
 *
 * Bảng màu (tông tin cậy, cao cấp):
 *   --s4u-ink     #1f2a29  chữ đậm
 *   --s4u-body    #3a4544  chữ thường
 *   --s4u-muted   #6b7775  chữ phụ
 *   --s4u-line    #e7edec  viền
 *   --s4u-panel   #f6faf9  nền nhạt
 *   --s4u-green   #18a558  nhấn (tick/uy tín)
 *   --s4u-green-d #0f7a40  nhấn đậm
 *   --s4u-orange  #ff6a13  CTA mua
 *   --s4u-zalo    #0068ff  Zalo
