- ImportedExerciseRepository: persistenza JSON degli import (titolo dal nome file, note con durate/bemolli, metro; max 50, più recenti primi) - FilePicker passa anche il nome del file (expect + 3 actual) - PracticeSetupScreen salva la sequenza importata prima di avviare - ExercisesScreen: sezione 'Importati' con anteprima e cestino - fix: picker desktop su Dispatchers.Swing con finestra parent (l'import XML congelava l'app: dialogo Swing su thread di background) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
