   soplis.css — SHARED DESIGN SYSTEM
   ------------------------------------------------------------
   NEW FILE. Every page now links this (plus styles.css, which
   previously existed but was linked by ZERO pages — which is why
   .grid-4cols on the homepage silently did nothing).

   Purpose: one source of truth for colour, type, spacing and the
   shared components, so Grocery stops looking like a different
   product from Marketplace.

   Rule going forward: purple is the PLATFORM. Each vertical gets
   an accent colour, but typography, cards, spacing, buttons and
   loading states stay identical everywhere.
