 * iOS safe-area fix:
 * Do NOT set a fixed `height` on #mbn-bar.
 * Instead, the bar has NO explicit height — it grows naturally
 * to wrap .mbn-bar-inner (which has height: var(--mbn-height))
 * PLUS padding-bottom equal to the safe-area inset.
 * This removes the phantom white gap below the buttons.
 *
 * z-index: 200000 keeps the bar visible above any open panel.
