   Toolbar Dropdown Components - Unified Styling
   ============================================
   
   Shared styles for toolbar dropdown buttons including:
   - ViewPickerDropdown
   - Draft/saved state indicators
   
   Design principles:
   - Compact, refined appearance
   - Consistent typography (13px, weight 500)
   - Subtle hover/active states
   - Smooth animations with appropriate easing
   - Use of design tokens for consistency
