/* /nav.css — Site-wide cream-index navigation
 *
 * Single source of truth for the shared header used on every page.
 * Loaded after /base.css + /style.css + /direction-b.css; on the homepage
 * it loads alongside /homepage.css.
 *
 * Body-class contract:
 *   body.home              — transparent header over a dark hero photo;
 *                            colour flips to cream + dark text when any
 *                            drawer opens (.is-nav-open class via /nav.js).
 *   body.has-light-header  — header sits in the cream + dark text state
 *                            by default; drawer just opens, no colour flip
 *                            needed (header is already in the "open" state).
 *
 * Active-state contract:
 *   The matching top-level <button> or <a> for the current section gets
 *   aria-current="page". A small olive dot renders after the label.
 *
 * Mobile (<1024px): the existing nav breakpoint hides .header-nav and
 * shows the mobile drawer. Cream-index drawers don't render below the
 * breakpoint — same behaviour as before.
