/* ============================================================
   Shichang Textile — Global Design System
   Nantong Shichang Textile Co., Ltd. | Pure CSS/JS (CMS-friendly)
   ------------------------------------------------------------
   Design principles:
   - Typographic hierarchy: H1 -> H2 -> H3 clearly differentiated
   - Single accent color family, managed via CSS variables
   - Responsive: mobile (<768px) / tablet (768-1024px) / desktop (>1024px)
   - Motion: GPU-only properties, prefers-reduced-motion respected
   - No AI-slop: restrained surfaces, no gratuitous gradients/glassmorphism
