/**
 * SOFT4U — Single product redesign (CSS) — bản dọn lặp + chuẩn font-weight
 *
 * Nguyên tắc:
 *   - Mọi class prefix `s4u-product-` / `s4u-cmp-`.
 *   - Rule layout "mạnh" scope dưới `.s4u-product-redesign` (body class).
 *   - KHÔNG đổi màu/format khối giá (#custom-price-display, .price) — chỉ căn khoảng cách.
 *
 * Quy tắc font-weight (KHÔNG dùng 750/800/850/900 nữa):
 *   - tiêu đề lớn / tiêu đề phụ / box title : 700
 *   - button / label                        : 600
 *   - nội dung mô tả                         : 400
 *   - nội dung nhấn nhẹ                      : 500
 *
 * Bảng màu:
 *   --s4u-ink   chữ đậm   |  --s4u-body chữ thường  | --s4u-muted chữ phụ
 *   --s4u-line  viền      |  --s4u-panel nền nhạt
 *   --s4u-green nhấn      |  --s4u-green-d nhấn đậm | --s4u-orange CTA | --s4u-zalo Zalo
