   Honda — Trang liệt kê bài viết (hub Kiến thức xe Honda + danh mục)
   template-parts/blog-archive.php. Thiết kế lại theo mockup 22/10/2026, áp DESIGN_SYSTEM.md:
     hero navy (+ ảnh showroom mờ dần bên phải) → nền xám nhạt (--color-surface-alt):
     chip danh mục + sắp xếp, lưới thẻ trắng 2 cột + sidebar, khối "Khám phá xe" nền đỏ nhạt.
   Không đổ bóng; mọi màu qua token. Mobile first: chip cuộn ngang, một cột, hit target ≥40–44px.
   Breakpoint: 768 (lưới 2 cột) · 1024 (sidebar 320px sticky).
