/*
 * mobile-nav.css — mobile-only responsive layout.
 *
 * Hamburger button, slide-out drawer, and media queries that swap
 * the desktop top nav / sidebar for the mobile drawer.
 * Active when top_level_folders_as_top_control is true.
 *
 * Breakpoint: 768px  (matches docsify's built-in mobile cut-off)
 *
 * When adding new features:
 *   1. Build the desktop version in bruha.css / its own CSS
 *   2. Add the mobile representation here
 *   3. Use the @media block at the bottom to show/hide
