/* =========================================================
   NoStash Studio — page de redirection Discord

   Identité visuelle, tirée du logo :
   - palette : violet #5B4FE0 → #2E2570 sur encre #161221 ;
   - formes : les chevrons < > du logo (coins de la carte) ;
   - ton "code" : police monospace pour les petits textes,
     curseur clignotant, grille en fond.

   Les animations ne modifient que transform, opacity ou
   stroke-dashoffset : pas de recalcul de mise en page.
