Design Patterns

Pattern	Implementation
Finite State Machine	Player states (IDLE → COUNTDOWN → PLAYING ↔ PAUSED)
Reducer Pattern	Centralized state management via useReducer
Service Pattern	AudioService & CustomExerciseManager - pure JS, testable
Composition	Granular components (TabNote → TabString → TablatureView)
Config Centralization	All constants in /config
