/* Several rules below set an explicit `display` on elements that also get toggled via the
   `hidden` attribute (#loginView{display:flex}, .item-form label{display:block}, etc). Author
   rules always beat the browser's default [hidden]{display:none} UA-stylesheet behavior, and a
   plain attribute selector here wouldn't out-specificity an ID selector either — !important on
   one blanket rule is the standard fix so [hidden] always wins regardless of what else targets
   the element. */
