 * The site header, shared by every page (home, pricing, legal, docs, guides).
 * Pages link this file and use the same markup, so the logo, links and
 * buttons sit in the same place at the same size everywhere:
 *
 *   <header class="site-nav"><div class="site-nav-inner">
 *     <div class="site-start">[docs: .menu-toggle]<a class="site-logo">Min<span>Pin</span></a></div>
 *     <nav class="site-links">…</nav>
 *     <div class="site-actions"><button id="themeToggle" class="theme-toggle">…<a class="site-cta">Download</a></div>
 *   </div></header>
 *
 * Colours come from each page's tokens (--bg, --fg, --muted, --card, --border, --accent).
