/* ============================================
   RenDS — Primitive Shadow Tokens
   ============================================
   Soft, Apple-style layered shadows.
   Each level uses two shadows for realism:
   one for ambient occlusion, one for key light.

   NOTE: The actual --shadow-xs through --shadow-2xl
   values are defined in semantic/colors.css using
   light-dark() color tokens for automatic dark mode.
   This file defines shadow-independent primitives only.
