/* ==========================================================================
   BELMARK — Design System (tokens, base, tipografia, layout)
   --------------------------------------------------------------------------
   Identidade monocromática derivada da logotipo (monograma BMK). A interface
   é clara — papel off-white, superfícies brancas, tinta grafite — e usa
   zonas escuras pontuais (sidebar, rodapé, players de vídeo, CTA final)
   para mesclar o preto da marca com o branco.

   CORES (tema claro)
     --belmark-background  off-white quente — fundo das telas
     --belmark-surface     branco — cards, inputs
     --belmark-surface-2/3 cinzas claros — hover, trilhas, estados
     --belmark-primary     grafite quase preto — ação principal, títulos
     --belmark-secondary   grafite médio — ação secundária
     --belmark-text / --belmark-muted / --belmark-subtle — hierarquia de texto
     --belmark-border(-strong) — divisórias finas
     success / warning / danger — apenas para estado, nunca decoração.

   ZONA ESCURA  .theme-dark (e .sidebar, .site-footer, .final-cta, .video)
     redefine os mesmos tokens para grafite; componentes funcionam igual.

   TIPOGRAFIA
     --font-display Inter Tight — títulos (tracking negativo, peso 600)
     --font-body    Inter — texto corrido e interface

   ESPAÇAMENTO  --space-1 (4px) … --space-10 (96px), múltiplos de 4
   RAIO         --radius-sm (6) / --radius (10) / --radius-lg (14) / pill
