   BLEND IDEAS — Header e rodapé para as LANDING PAGES existentes
   site-2026/assets/css/blend-nav.css

   POR QUE ESTE ARQUIVO EXISTE, E NÃO O blend.css
   As LPs de segmento já estão no ar, foram feitas à mão e têm CSS inline
   próprio. O blend.css tem reset global (`* { margin: 0 }`, regras em
   body, h1..h4, img, a) que QUEBRARIA o layout delas.

   Este arquivo:
     - não tem reset global
     - não estiliza nenhuma tag solta (nada de `body`, `h2`, `img`, `p`)
     - usa o prefixo `bi-` em toda classe, para não colidir com as classes
       das LPs (que já usam .container, .footer-grid, .btn e afins)
     - declara os próprios tokens dentro de escopo, não no :root

   Tokens idênticos aos da marca. Nenhum valor inventado.
