/* Several elements below are shown/hidden by toggling the `hidden` attribute from JS,
   but also carry an unconditional `display: flex` class rule (e.g. .modal-overlay,
   .conv-active). An author-stylesheet `display` declaration beats the browser's
   default `[hidden] { display: none }` rule regardless of selector specificity, so
   without this it silently stays visible. Force it, unconditionally. */
