   14. CURSEUR PERSONNALISÉ  (build 5.2)
   ────────────────────────────────────────────────────────────────────
   Remplace la version qui vivait dans gritty.js / gritty.css et ne
   fonctionnait donc que sur l'accueil. Trois corrections de fond :

   1. z-index maximal — l'ancien (99991) passait SOUS certains panneaux ;
      ici rien ne peut le recouvrir.
   2. Plus de traînée de fumée : les bouffées grises se voyaient sur les
      fonds sombres (palette, lightbox, modales) et salissaient l'écran.
   3. Le curseur natif revient sur les champs de saisie : masquer le
      « I » de texte rendait les formulaires pénibles à utiliser.
