/* ============================================================================
   SEO programático — /q, /v, /bncc
   Porte fiel do <style> inline das telas legadas (QuestoesTopico.aspx, etc.).
   NÃO pode ser CSS isolado (.razor.css): o conteúdo denso (questões, intro, BNCC)
   é injetado como MarkupString/HTML cru, que não recebe o atributo de escopo do
   Blazor — então as regras precisam ser globais. Fica FORA da página (aqui),
   linkado via <HeadContent> em cada tela. Namespaced por prefixos próprios
   (.seo-*, .q, .intro-*, .bncc-*, .hero, .cta-*, .res-*, .rel*, .faq-*) pra não
   colidir com o shell autenticado do app.
