 * The "Failed to access camera/microphone" gritter notifications spawned by
 * showUserMediaError() are sticky and span the top of the editor. Without
 * this rule, the gritter's container/items intercept pointer events on the
 * editor underneath (Playwright's stability check fails with "subtree
 * intercepts pointer events"), making the pad unusable until the user
 * dismisses each toast. Pass clicks through everything except the close
 * button so the toast stays visible and dismissible without blocking
 * the editor.
