/* ============================================================
   Trang "Lý do chọn HUFLIT" — module why-huflit-page (SELF-CONTAINED).
   Port từ _design-reference/HUFLIT-standalone-260715/assets/css/site.css.
   Conditional enqueue: chỉ trang có block acf_fc_layout tiền tố "whyhuflit_".

   ⚠ SCOPE BẮT BUỘC: mọi rule component đặt dưới `.hf-page` (wrapper <main> của trang này).
   Lý do: các class dùng chung (.hf-shell, .hf-section, .hf-eyebrow, .hf-btn, .hf-crumb…)
   cũng được HEADER/MEGA-MENU + FOOTER dùng. File này load SAU mega-menu.css → nếu để class
   TRẦN sẽ ĐÈ định nghĩa gốc, làm mega/footer trên trang này bị co. Mọi module khác đều scope
   (`.hf-pd .hf-shell`, `.hf-pgp .hf-shell`, `:where(.hf-khoa) .hf-shell`…) — theo đúng convention đó.
   Namespace RIÊNG của module = hf-why5-* (cũng scope cho nhất quán).
