/**
 * VettID shared navigation styles: the header chrome (frame, logo, Coming
 * Soon chip), the hamburger toggle, slide-out menu chrome, and the desktop
 * inline nav (>=1024px). Loaded by every page alongside assets/site.css,
 * AND by /playbooks/* (separate repo, same CloudFront distribution).
 *
 * This file is the ONLY place header/nav chrome may be styled. site.css and
 * the playbooks repo must not redefine these selectors — both repos' check
 * scripts enforce that. That's what keeps the nav identical across sections.

/* ── Header chrome ──
   Main-site pages use a bare <header>; playbooks marks it <header class="site">.
   The element selector covers both (page-top header only — neither site nests
   <header> elsewhere). var() fallbacks keep this file self-contained. */
