   HOW THIS FILE IS ORGANISED (search for these headers):
     1. DESIGN TOKENS   — every colour, font, and spacing value
                           lives here. Change a value once, it
                           updates the whole site.
     2. RESET & BASE     — sensible defaults for every element
     3. LAYOUT HELPERS   — reusable containers/sections
     4. NAV
     5. HERO
     6. TRUST BAR
     7. ABOUT
     8. BUILDS (product cards / spec sheets) + builds teaser + callout
     9. HOW IT WORKS
     10. SERVICES (repairs)
     11. TESTIMONIALS
     12. SUPPORT (FAQ + contact)
     13. FOOTER
     14. RESPONSIVE (small screens)

   You almost never need to touch anything below section 1 just
   to restyle the site — try changing the tokens first.
