Powerstone blesses a number already played this turn

On the table the stone and the number land together; digitally the
display can come a beat late and the +1 silently vanished. Displaying
POWERSTONE now grants the stride retroactively when a number was
already played for movement this turn, with a chronicle line so the
gain is visible. Pure widening — no rev needed.
