/* ==========================================================================
   Kolkata Kiddathon 2026 — site header + footer
   WS4a created this file; WS4b rebuilt the header layer MOBILE-FIRST to match
   design/option-a-canopy-v4.html (the approved mockup):
     - both partner medallions stay visible on phones (client: "the top 2 logos
       are not visible")
     - the mobile brand mark is the full wordmark INCLUDING "10th Edition";
       the flat no-edition lockup + .kd-brand-txt take over from 768px
     - header box is 64px on mobile / 76px from 768px
   Loaded on EVERY page, so every selector here is namespaced under .kd-*.
   Nothing here touches a bare element selector except the :root token block,
   so Bootstrap and the legacy style.css on the inner pages are left alone.
