/* ==========================================================================
   Encaixa — Component Styles
   ==========================================================================
   Reusable UI components built on design tokens.
   Depends on css/tokens.css and css/base.css (import in that order).

   Spacing & token usage checklist:
     ✓ All padding/margin → var(--space-*) tokens
     ✓ All colors → var(--color-*) or semantic aliases
     ✓ All border-radius → var(--radius-*) tokens
     ✓ All shadows → var(--shadow-*) tokens
     ✓ All transitions → var(--transition-*) tokens
     ✓ No hardcoded pixel values for layout (use rem/spaces only)
     ✓ No redundant CSS variable definitions (tokens defined once in tokens.css)
