/* ==========================================================================
   Red Roof Property Search — Design System & Components
   Mobile-first. Reuses Red Roof's warm, trusted-advisor brand language for
   marketing sections, with a denser "data mode" scale for search/listing
   UI (see audit: listing grids need tighter internal card spacing than
   editorial marketing content).

   NOTE ON COLORS/FONTS: values below are inferred from the current live
   site's warm off-white / warm-gray / red-roof-accent palette. Replace the
   --redroof-* custom properties with exact brand hex codes and font-family
   names once provided — every component below references these variables,
   so a correction is a one-place edit.
