   Aesthetic Token System - Default Values (Balanced)

   These CSS custom properties control the visual "feel" of components:
   - Border radius (sharp to rounded)
   - Spacing scale (compact to spacious)
   - Border widths (thin to thick)
   - Shadows (flat to elevated)
   - Typography (font and leading)

   Values are overridden by JavaScript when user selects a different aesthetic.
