/* ==========================================================================
   STUDIO TYPOGRAPHIE — Fiche outil
   --------------------------------------------------------------------------
   Feuille autonome de la modale ouverte par le bouton INFOS, construite par
   scripts/fiche.js : en-tête, six onglets de chapitre, afficheur animé,
   ceinture entrée/sortie/raccourcis et pied de page.

   À charger APRÈS ../styles/tool-header.css. Les classes internes sont
   préfixées `lf-` : la fiche est injectée dans une page qui possède déjà ses
   propres .glyph ou .specimen. Les jetons de couleur sont figés ici pour que
   la fiche ignore les variantes de --paper / --acid du studio.

   Accent du studio : jaune.
