   CSS architecture inside this standalone file (master prompt §36):
     1. syh-tokens      — design tokens (colors, radii, shadows, type, layout)
     2. syh-base        — scoped reset, type scale, layout helpers, buttons
     3. syh-components  — header, footer, breadcrumb, trust, FAQ, sources…
     4. syh-shop        — page-specific: hero, SKU grid, filters, dark band
     5. responsive      — 1100 / 840 / 620 breakpoints (site-wide standard)
   Max content width: 1350px
