/**
 * Header (W1, 2026-10-25). Desktop (≥ 1100 px): Header 10 "Signature" (Design 03), a white bar with
 * the logo and wordmark, the approved multi-page navigation divided by hairlines (Services is a
 * disclosure), the phone set large at the right with "Free estimate" under it.
 * Below 1100 px: the approved compact header (Figma R / Header 740:750): a 72 px bar, a square logo
 * (size/logo 52 / 48 / 40), the wordmark, and on phones a 44 px call button and a 44 px menu button,
 * on tablets the phone number and a labelled "Menu" button. The menu opens the panel of
 * Figma R / Menu Panel 740:923: full screen on phones, a 420 px drawer on tablets.
 * Markup: parts/header.html + inc/navigation.php (publication-aware links). Mechanics: assets/js/site.js.
