     expect to pull-to-refresh instead). It no longer conflicts with the

     itself now has touch-action: none (stops the browser from ever
     recognizing a scroll/refresh gesture starting there, regardless of

     via lockBodyScroll() in app.js, so there's nothing scrollable back

     on the sheet. If a conflict ever resurfaces, this is the line to
