   3. BUTTONS
   Skeuomorphic button system with physical depth and tactile feedback.

   Design rationale:
   - Multi-stop gradients create a lit-from-above appearance
   - Inset shadows add inner depth (highlight top, shadow bottom)
   - Text shadow makes text feel embossed into the button
   - Transform on hover creates physical "raising" effect
   - Layered box-shadows build realistic depth (near + far shadows)
