/* DDR principal · camada pedagógica (Trilhas e Aula)
   Porta a Camada Pedagógica V1 aprovada (Astro/Codex) para o site, no escopo #ddr-base: superfícies base,
   papel, recuo e contraste; bordas sutil, padrão e de campo; sombra só para a nota editorial. Laranja é a
   ação; o verde de apoio (#D5E52D) marca só aprendizado, progresso e concluído. Sem motion. */
