/**
 * Evident ICU Docs Mobile Foundation
 *
 * Purpose:
 * On narrow screens (<=860px) the docs sidebar is an off-canvas drawer,
 * hidden by default and opened via .docs-sidebar-toggle. Desktop (>=861px)
 * keeps the normal sidebar layout from docs.css.
 *
 * Contract (mirrors site-drawer-foundation.css):
 * - body.docs-drawer-open  -> drawer visible, page scroll locked
 * - .docs-sidebar.is-open  -> visible
 * - .docs-sidebar-toggle[aria-expanded="true"] -> active
