/* ══════════════════════════════════════════════════════════════════
   RetainCLM Visualization Library - renderer + landing section styles
   ------------------------------------------------------------------
   Loaded by BOTH the landing page (auth/login.html, for its Chart
   Intelligence section) and /charts. Split out from charts.css so the
   landing page pays for the renderer and its own six cards, and not
   for the whole feed/detail page stylesheet it never uses.

   Everything here is either .rcv-* (drawn by rc-viz.js) or .ci-*
   (the landing section's cards). Nothing else on the landing page is
   touched - the tokens below repeat the values already declared inline
   in login.html, so if this file were removed the landing page would
   lose the section's styling and nothing else.
