/* =========================================================
   PAGE: ABOUT US
   Tái dùng đúng design tokens + typography scale đã có (variables.css,
   typography.css) — không tạo màu/font mới. Bố cục kể chuyện tuyến tính:
   Hero → Story (ảnh + chữ) → Milestone (mốc thời gian) → Values (3 cột,
   cùng nhịp .dx-mono index như process-steps.css) → Closing/CTA.
