PlayerGrain

Remarks

⚠ Every grain in this assembly is this thin, on purpose. The logic is a plain class that a test constructs and drives; the grain supplies the one property the logic depends on and cannot provide for itself — that it is never re-entered. Writing the state machine inside the grain would make it untestable without a silo, which is how a coordination layer ends up with no tests at all.
