/* =========================================================================
   Shabazz Enterprise Publishing — site styles
   Hand-built, dependency-free. Organized top-to-bottom:
     1. Design tokens (CSS custom properties)
     2. Reset & base
     3. Layout primitives (container, section, headings)
     4. Buttons
     5. Accessibility helpers (skip link, sr-only, focus, reduced motion)
     6. Header / navigation
     7. Hero
     8. About + services + genres + signature
     9. Book cards + catalog grid (frameless, no-crop covers)
    10. Get-published section (business card)
    11. Footer + scroll-to-top
    12. Responsive refinements

   To restyle the whole site, edit the tokens in section 1 — everything
   downstream reads from them.
