   Brand direction: an Indian local-marketplace feel — warm,
   trustworthy, distinct from OLX's corporate blue. Deep wine/
   maroon as the primary (signals trust + is memorable against
   every blue-branded competitor), warm marigold as the single
   accent (reused consistently for CTAs, the verified badge,
   and "new" tags — not scattered across random elements).
