/**
 * Variant CSS: nav--sidebar-drawer-trigger
 *
 * Minimal top bar — brand left, a labelled "Menu" hamburger button right —
 * implying a side drawer. The full navigation lives in a panel that slides in
 * from the right edge (all viewports), keeping the bar itself ascetic so the
 * page content dominates. Uses the chrome tokens (--text-primary /
 * --background / --background-dark / --text-on-dark / --divider-primary /
 * --accent). Scope: body.aibt-universal .universal-nav--sidebar-drawer-trigger.
