/* ==========================================================================
   FiberPlan Design System — v5.0 Enterprise
   ==========================================================================

   Camada de refinamento. Ela vem depois de tudo de propósito: redefine tokens
   e ajusta componentes pela cascata, sem renomear uma classe sequer. Nada de
   HTML precisou mudar para esta camada entrar, e remover este bloco devolve o
   sistema exatamente ao visual anterior.

   O que mudou, e por quê:

   1. Neutros mais frios e mais claros. O fundo anterior (#eef2f7 com dois
      gradientes radiais grandes) puxava azul e "sujava" o branco dos cards.
      Software corporativo de 2026 é mais plano: o gradiente encolheu e virou
      quase imperceptível, e o contraste passou a vir da borda, não da sombra.

   2. Escala tipográfica em tokens. Antes cada componente tinha o seu tamanho
      em px solto — 13.5px aqui, 12.5px ali. Agora existe uma escala, e o que
      dá a sensação de produto caro é justamente ela ser respeitada.

   3. Densidade de tabela. Dado numérico ganhou fonte tabular (algarismo de
      largura fixa), cabeçalho ficou mais leve e a linha, mais alta. Tabela de
      LPU e de licenciamento são o que o engenheiro olha o dia inteiro.

   4. Foco visível de verdade. Anel de foco consistente em tudo que recebe
      teclado — é acessibilidade, e é também o detalhe que separa um sistema
      interno de um produto.

   5. Movimento com freio. Transições curtas, e `prefers-reduced-motion`
      respeitado: quem configurou o sistema para não animar não vê animação.
