   XFOOT AI VISUAL LANGUAGE
   Un seul langage visuel pour tout ce qui vient de l'IA Xfoot (Score,
   Confidence, Value, Model, Arena, Signal). Pas d'effet excessif : pas de
   glow massif, pas de gradient partout — un marqueur "XFOOT AI" + la
   couleur --x-primary utilisée avec parcimonie (prompt §18).
