   Portal Dúvidas — help centre
   Locked to portalduvidas.com.br. Served at /assets/theme.css.

   Two halves:
     1. the template's own chrome (header, hero, subject cards, bands, footer)
     2. the ENGINE's markup — .article*, .post-*, .toc, .faq, .result*,
        .pagination, .table-wrap. A template that skips half 2 ships a
        beautiful home and a naked article.

   Colour, font, container and radius tokens are set per-site in layout.php;
   everything below consumes them.
