/* ============================================
   RealtyIndex — project stylesheet

   Loads AFTER indexbychi.css. Everything here is
   specific to RealtyIndex: property cards, the search
   and filter bars, the hero, page-level layout.

   Shared tokens, base elements, the logo lockup,
   buttons, badges, tables and number treatments live
   in indexbychi.css. Do not redefine them here — and
   never edit indexbychi.css in this repo.

   Every colour below is a token from indexbychi.css.
