/* ============================================================
   eigenform — shared design system
   Accent is the mint from the logo: rgb(73,172,153) = #49AC99.

   Two structural convictions carried across every page:
   1. The page is the outermost container, and it has corners.
      Nothing inside may carry a radius >= its container, so all
      block-level panels are SQUARE. Radius zero, stated, not
      defaulted. Inline code is the sole exception: text-proportion
      radii, too small to notice — which is the point.
   2. Gradients are fourth-rank in contrast. They hint depth at the
      thematic breaks and never announce themselves. On paper they
      would be non-printing; here they are simply quiet.
