A first click on a character at the select screen lagged; a repeat did not. In 1.12.1 the select's model build ends on `IsReady(1, 1)` over the scene (`0x473083` → `0x710450`), which loads the scene, the character, its items and the pet before returning. A failed read counts as done (`0x4434a8`). So the stage draws whole in the frame after the click.
benilla built the stage one asset step per frame, so a first select took 4 to 10 frames. A select now holds the next frame until the whole stage has loaded or failed, uncapped. A mesh built in that wait is built whole; the old vertex budget had cut the human booth model's skinned forms on first spawn.
Measured with the new `gsel` trace: a first select now draws whole in 3 frames. Tests cover the wait, a failed read and a return.
