Story phase 2: the transformation and the prologue

At match point of an act's cup final the beaten finalist does not fall.
The ceremony lands (the loot, still a plain card), then the applause is
cut, the camera closes in, and on the turn he bursts and the act's boss
stands where he stood, growing into the frame with his name and
"GAME 10". He runs out of the picture to the left while the stands empty
onto the court, and game 1 of the chapter begins without a cut: the
crowd that came down is its first wave. The interlude holds serving,
spawns and the boss's AI through the scene.

The prologue is one game of tennis against a living opponent with the
old transformation exactly as written; when it hands over, act I's cup
takes the court. Two new tests. v380, staging only.
