/* ============================================================================
   NoVolante Design System — v1.0 (2026-04-19)
   ----------------------------------------------------------------------------
   Fonte única de verdade para UI do NoVolante. Todo CSS específico de tela
   consome os tokens (variáveis CSS) e componentes (classes .nv-*) deste arquivo.
   Não adicione aqui CSS que seja feature específica — use escopo local na view.

   Organização:
     1. Tokens (cores, tipografia, spacing, elevação, motion, radius, z-index)
     2. Reset + base
     3. Componentes (alfabética): alert, badge, btn, card, check, empty-state,
        field/input/select/textarea, kbd, modal, skeleton, spinner, switch,
        table, tabs, tag, toast, tooltip
     4. Layouts helpers (grid, stack, flex)
     5. Utilidades (text, spacing, border, bg, truncate, sr-only)
     6. Responsivo
     7. Print
     8. Dark mode (preparado, ativa via [data-theme="dark"] no html)
