/*
 * The widget renders fixed-position overlays from inside its shadow root. Those
 * still compete with this page's own stacking, so the host has to hoist it above
 * the sticky nav (200) and the persona dropdown (9999) — otherwise the docked
 * panel's header controls sit under the nav on shorter viewports, where the
 * panel's top edge lands within the nav's 56px band.
