# Bewegungssystem:
#   • Kein Ziel + kein Walk    → Souls-Modus: Charakter dreht sich zur Laufrichtung
#                                 (relativ zu camera_pivot.world_yaw), Animation = "run"
#                                 RMB gehalten: A/D = Strafe statt Drehung
#   • Kein Ziel + Walk (NumLock) → RPG-Modus: Strafe-Animationen, langsame Geschwindigkeit
#   • Ziel markiert            → Lock-On: Kamera dreht Spieler zum Ziel,
#                                 WASD = Strafe/Rückwärts relativ zur Spielerausrichtung
#
# Kamera-Referenz:
#   dir3 (Bewegungsvektor) nutzt camera_pivot.world_yaw im Souls-Modus, damit sich
#   der Vektor NICHT mit der Spielerrotation dreht (kein Feedback-Loop).
#
# Kampf:
#   Autoattack, Heavy Strike (Krieger), Quick Strike (Schurke), Frostbolt (Magier)
#   Global Cooldown, Skill Cooldowns, Cast-System
#
# Animationen:
#   Werden zur Laufzeit aus FBX-Dateien geladen (_load_anim_from_fbx).
#   Root Motion wird automatisch entfernt (_strip_root_motion).
