/* Several rules below (.view, .modal-overlay, .login-screen, .progress) set
   an explicit `display` on elements that are also toggled via the `hidden`
   attribute (login gating, tab switching, the Add User modal). Author CSS
   always wins over the user-agent stylesheet's `[hidden] { display: none }`
   default, regardless of specificity -- so without this rule, `el.hidden =
   true` stops visually hiding anything once a later rule sets `display` on
   that element. This keeps `hidden` authoritative no matter what else
   targets the element. */
