-/// Cet écran est volontairement minimal : un Scaffold dont le body est

-/// l'InteractiveViewer reçoit les deux doigts sans concurrence avec un
-/// scroll vertical ou une transformation parente.
-///
-/// Interactions :
-///   - Tap                    -> ajoute TOUJOURS un impact, même juste à côté
-///                               (ou par-dessus) un impact existant. Aucun tap
-///                               n'ouvre d'édition de score : on peut donc
-///                               placer un impact au pouce près sans être
