/* ============================================================================
   ACADEMY — folha única do módulo Courses (área do aluno + comunidade).

   Substitui os ~11 KB de <style> inline que eram retransmitidos em cada uma das
   ~13 páginas da jornada (e eram emitidos DENTRO do <main>, gerando HTML inválido).
   Agora é um arquivo cacheável, com camada de tokens própria.

   CONTRATO WHITE-LABEL
   Nenhuma cor literal abaixo da seção de tokens. Tudo deriva de --gx-* (que o
   brand_helper redefine por install a partir de brand_settings), então trocar a
   paleta da marca no banco re-tinge o Academy inteiro sem tocar em CSS.
   Os fallbacks embutidos reproduzem a paleta de origem, para que a folha continue
   legível se carregada sem o token sheet.
