 * Widget "Cabeçalho" — FJPN Site

 * Fonte: architecture/secoes-design.md (seção "1. Navbar") e

 *
 * Paleta própria (--fjpn-header-*), distinta da paleta do corpo do site —

 * `.js-ready`, adicionada pelo header.js assim que o script roda, é quem
 * liga o comportamento recolhido/flutuante controlado pelos botões
 * (ver decisão registrada no topo de widgets/header.php).
