Unlocks and milestones

Each fair opens the next pack of pieces in four milestones: pass arc 1, pass arc 2, reach the boss, win.

The base pool is available from the first run. Every other piece belongs to a fair's pack and unlocks the first time you reach a milestone ON a specific fair (campaign, any Heat; the short show counts): M1 pass arc 1, M2 pass arc 2, M3 reach the boss, M4 win the show. Milestones also pay tickets the first time.

Winning a fair opens the next one. Daily, practice, LAB, Marathon and Endless runs never unlock milestones. The last fair's milestones only pay tickets; winning it opens the post-game. The fair pages list what each milestone unlocks.
