/* Bharat Brumhmaan site — plain HTML+CSS, no build step, no JS framework.
   Server-rendered by design: every page is real, crawlable text, unlike the
   Flutter/CanvasKit app. Rebuilt to match the Marblism/Walter-built
   reference site's actual design system precisely (colors converted from
   its OKLCH tokens, grid proportions and type scale read from its DOM) —
   full dark theme throughout, no split light/dark treatment. */
