/* =============================================================================
   Aamal Aljoud — Redesign Design Tokens
   -----------------------------------------------------------------------------
   Single source of truth for the site AND the dashboard.
   Values were measured from the approved home page design (the master
   visual reference) and then normalised into a coherent ramp.

   Scope: both. The dashboard loads this same file and then maps these
   values onto its own chrome in dashboard-assets/css/dashboard.css, so the
   two halves of the product cannot drift apart: a colour changed here
   changes in both.
   Load order: this file must come AFTER all legacy stylesheets.
