 `DATA` 신규 이벤트 악곡 HoloHawk, Mekurumeku Rendezvous, Tri-Unity♡LoveSystem의 모든 난이도 채보와 점수 계산 데이터를 반영했습니다.
 
+`DATA` 시시로 보탄의 Simulacre를 추가했습니다. Easy·Normal·Hard·Expert 채보와 곡별 점수 계산을 지원합니다.

 ### 액티브 미발동 시뮬레이션
 
 `NEW` 배치 분석의 카드별 액티브 구간을 클릭해 해당 발동을 제외한 예상 점수·이론상 고점과 그래프를 확인할 수 있습니다. 다시 클릭하거나 모두 복원하면 원래 결과로 돌아옵니다. 그래프 근처에서 현재 최고점·원래 대비 변화와 각 토글 직전·직후의 점수 차이를 확인할 수 있습니다.
