/* A same-specificity author rule (e.g. .btn/.account-menu { display: flex }) otherwise beats
   the browser's own [hidden] { display: none } default, since author styles always win over
   the UA stylesheet regardless of declaration order — found live via Playwright: auth.js's
   [data-auth-logged-out]/[data-auth-logged-in] toggle set the `hidden` attribute correctly,
   but the element stayed visually visible because .btn/.account-menu's own display rule
   overrode it. One global override here covers every current and future hidden-toggled
   element instead of patching each class individually. */
