/*
 * AIZZTECH site navigation for the standalone static Rencana pages.
 * Mirrors the React `Header` component at `components/Layout.tsx` so the
 * nav looks identical regardless of which page (React or static) you're on.
 *
 * The brand assumes the colour-scheme of the React app *when scrolled*:
 * dark navy background with light text. That's appropriate here because
 * these are interior pages, not the home hero.
