/* ============================================================
   CAMADA PREMIUM — código canónico partilhado pelos seis sites
   (fartapao, bracarapipe, mesteze, noniussoftware, talkdesk, tibagroup).

   Como usar: copiar este bloco para o FIM do style.css do site e
   (1) mapear os tokens abstratos no :root do site:
         --realce: var(--marca);            tinta do site
         --realce-forte: var(--marca-forte);
         --realce-suave: color-mix(in srgb, var(--marca) 22%, transparent);
         --tinta-sobre-realce: #fffaf0;     texto sobre --realce-forte
   (2) apagar as regras antigas que este bloco substitui:
         .revela / .em-vista, .botao-tema .icone-* (display:none),
         .nav-principal a:hover / [aria-current] com pastilha de fundo,
         .btn:hover / .btn:active simples, .cartao/.cartao-destaque hover.
   (3) ajustar a escala do h1 do hero à tipografia do site (ver «HERO»).
   Requer html.js (script inline no <head>) e o main.js canónico.
   Tudo o que esconde conteúdo vive sob html.js + no-preference.
