/* =========================================================
   Seller Signal — sales-focused theme
   Bebas Neue (display) + Roboto (body) on red/black/white

   Design system
   -------------
   Every spacing and font-size value on the site is drawn from
   the scales below. That is what keeps padding, gaps and text
   sizes equal across all five pages instead of drifting into
   one-off pixel values per page. Large/display sizes use fluid
   clamp() so type and rhythm scale smoothly with the viewport
   (verified down to 360px) instead of jumping at breakpoints.
