   Nạp SAU style.css: dùng chung token :root, header, menu, footer, nút, lightbox, con trỏ, TBC…
   File này chỉ thêm khối .pj-* (trang dự án) và .pjx-* (trang danh mục). Trang do tools/build-projects.rb sinh ra.
   Chuyển động: assets/js/project.js (GSAP + ScrollTrigger + Lenis). Không JS / giảm chuyển động → bố cục tĩnh, đọc được đầy đủ.
