   Sticky architecture:
     Both bars use position: sticky. The announcement bar sticks
     at top: 0 (z-index: 51). The nav sticks at top: var(--announcement-h)
     (z-index: 50) so it nestles directly below the announcement bar.
     The mobile drawer uses position: fixed offset by the combined
     height of both bars. If announcement bar padding changes,
     update --announcement-h to match.
