/*
 * In-app help assistant widget.
 *
 * Anchored bottom-RIGHT, the corner people reach for.
 *
 * That corner is also where _NotificationCenter.cshtml puts its toast container
 * ("bottom-0 end-0"), so the two are kept apart deliberately rather than left to overlap:
 *
 *   - While the launcher alone is showing, toasts are raised just above it.
 *   - While the panel is open, toasts move to the bottom-LEFT, which is free.
 *
 * Both rules live at the end of this file. If you move the widget again, move those with it.
 *
 * Built on the Bootstrap 5.3 CSS variables already loaded by both layouts, so it inherits the
 * application's colours rather than restating them.
