/* ================================================================
   nav.css – gedeelde header + full-screen nav-overlay + logo-lockup
   Gebruikt door alle "self-contained" pagina's (index, offerte-aanvragen,
   projecten, diensten) die hun eigen :root-tokens definiëren:
   --c-primary, --c-secondary, --c-accent, --c-text, --c-text-light,
   --c-muted, --f-serif, --f-sans, --max, --pad, --ease, --ease-spring.
   Header-injectie gebeurt door nav.js in <div id="hdr-root"></div>.
   De .logo/.logo-wordmark/.logo-sub-classes worden ook hergebruikt
   in de (per pagina hardcoded) footer — zie ".footer-brand .logo-*"
   overrides in elke pagina voor de gedimde footer-variant.
