   Devhub Solutions — GO Landing v4 (layout chung cho landing + trang con)
   Direction: classic corporate trust palette (navy + sky blue), soft
   rounded cards, real photography, smooth GSAP ScrollTrigger reveals —
   the same recipe as well-executed 2018-era Bootstrap business templates,
   rebuilt with real content for GO (vận tải/logistics nhỏ, HTX vận tải).
   v4: bổ sung style cho các trang con dùng layout chung templates/landing/
       (page hero, blog list/filter, bài viết, dịch vụ, về chúng tôi, liên hệ)
