/*
 * Mobile Drawer.
 *
 * Focus management is handled by the `inert` attribute, not by visibility.
 * `visibility: hidden` inherits into children, and a hidden element cannot
 * receive focus — so opening the panel and immediately focusing inside it
 * failed while the inherited value was still resolving. `inert` removes the
 * subtree from the tab order and from assistive technology without touching
 * paint, so the transform can animate freely and focus() works on the frame
 * the panel opens.
 *
 * The attribute is present in the markup by default, which also means the
 * off-screen panel is unreachable when scripting is unavailable.
