   IMPORTANT : force l'attribut HTML `hidden` à toujours gagner.
   Sans cette règle, nos sélecteurs ID ci-dessous (ex: #idle-modal
   avec `display: flex`) ont une spécificité (1,0,0) qui écrase
   la règle user-agent par défaut `[hidden] { display: none }`
   (spécificité 0,1,0). Conséquence : un <div id="idle-modal" hidden>
   s'afficherait malgré tout. Cette règle globale empêche ce piège.
