   TAILWIND SHIM
   Substitui o Tailwind via CDN por CSS estático, cobrindo exatamente
   as classes utilitárias usadas neste projeto (não é o Tailwind
   inteiro — só o subconjunto realmente em uso).

   Por que isso existe: o CDN do Tailwind (https://cdn.tailwindcss.com)
   compila as classes em tempo real no navegador. Se o CDN cair, for
   bloqueado, ou o usuário estiver com internet ruim, todas as telas
   que dependem dele (Disciplinas, Comunidade, Configurações, Suporte)
   ficavam completamente sem estilo. Esse arquivo elimina essa
   dependência externa.
