+Shadows on Web communicate visual separation and hierarchy through composed box-shadow layers.

+Unlike iOS (single shadow token) and Android (dp elevation), web elevation is constructed
+from multiple shadow layers to simulate depth and ambient light.
+
+Each shadow level consists of predefined layered shadows.
+Components must use these tokens instead of defining custom box-shadow values.
+
+Higher levels combine stronger blur, increased offset, and additional ambient layers
