/* The browser hides `[hidden]` with a UA rule that ANY author `display:` rule
   outranks -- and several elements here are both `display:`-styled and toggled
   via `el.hidden`. Without this the empty-state message renders underneath a
   fully working activity, and the readout shows its headings with nothing in
   them. The `hidden` PROPERTY is correctly set in both cases, so neither a
   property check nor the console catches it; only looking at the page does. */
