   Design tokens are copied exactly from the real application's own

   marketing site's navy/red is genuinely the approved brand, not an
   approximation. Font is the product's own (Barlow / Barlow Condensed).
   Premium automotive-technology aesthetic: deep navy backgrounds, white
   typography, subtle red accents - enterprise SaaS, not a garage
