/* ==========================================================================
   chirayilgroup.com · v2 · Liquid Glass in the Chirayil palette
   --------------------------------------------------------------------------
   The material is the estate's shared Liquid Glass (kalikkalam/styles.css, as
   adapted for Kalavara): backdrop blur + saturation lift, the edge stack, a
   135deg specular sweep, an inner bloom. Decision (LD 2026-10-28): glass for
   the FRAME and short tiles; anything read at length sits on SOLID cards.
   Cormorant Garamond for the wordmark + headings (editorial), Rajdhani for UI.
   Dark only, like the rest of the brand's public pages.
