/* The [hidden] attribute hides via a UA rule (`[hidden] { display: none }`),
   which any class selector setting `display` outranks. `.gate` and `.empty`
   both set `display: grid`, so `el.hidden = true` silently did nothing and the
   login screen stayed over the app after a successful unlock. Assert it here
   rather than avoiding `display` in every class that might get toggled. */
