   então a página fala em duas vozes: a humana (Archivo/Inter, argumentos) e
   a da máquina (JetBrains Mono, tudo que o tracker emite: eventos, IDs,
   contagens, horários, status).

   Carregado DEPOIS de app.css. Tudo é escopado em .landing-body para vencer
   as regras de classe única do app.css sem quebrar app/blog/páginas legais.
   Nenhuma cor é hardcoded exceto as identidades reais dos canais (Meta,
   TikTok), então os 10 temas continuam funcionando.
