/* The HTML `hidden` attribute works by applying `display: none` from
   the browser's default stylesheet — which means ANY author CSS rule
   setting `display` on the same element silently overrides it. That
   caused a real bug: `.actions-row` and `.switcher` both set
   `display: flex`, so `hidden` was being ignored and the Add entry /
   Transfer buttons stayed visible to read-only users even though the
   JavaScript was correctly setting the attribute. This rule makes
   `hidden` authoritative everywhere, permanently. */
