/* =============================================================================
   Meridian Quant — sohub.digital-style rebuild
   Near-monochrome: pale page + carbon ink, ONE quiet blue accent. Oversized
   Inter that bleeds off the edge. Big radii, pill buttons, floating menu panel,
   stacked sticky cards, dark feature panels, a giant footer wordmark, and a live
   WebGL meridian globe. Depth from whitespace + hairlines, never heavy shadow.
