   base.css — il reset, gli elementi HTML, le animazioni condivise
   ============================================================================

   Caricato da base/_head.html subito dopo tokens.css. Qui stanno solo regole su
   ELEMENTI (html, body, ::selection, la barra di scorrimento) e le animazioni che
   più pagine riusano: niente che riguardi un componente o una pagina.

   Se una regola ha bisogno di una classe per esistere, non è di questo file.
