Best filming windows

• Be in position before downbeat: "bag TF up" has the strongest opener signal (100%).
• First 10-minute window: "come to brazil" often lands early (100%).
• Finale window: keep A-cam rolling for "NSFW" (closer probability 43%).
• Do not clear early: "why am i like this" is a common encore (100%).
• Set order is relatively stable. Pre-assign camera positions around recurring songs.
