/* ============================================================
   KARNA — Design System v4
   Theme: Paper & Circuit

   Philosophy:
   • Warm parchment is the ground. Calm, not cold.
   • Paper-grain texture: organic, hand-pressed beneath the surface.
   • Glass cards float above — frosted ivory, not dark mirror.
   • Cerulean-steel (#4f86c6) is the one neo note. Circuit, not coral.
   • The console IS the room. No seam between tool and feeling.

   To retheme: edit :root variables only.
