Rev 12: vanishing and water answer the call to arms

INVISIBLE's corner reads NEUTRAL/COUNTERACTION, and ANTI-ANTI's own
face names it an escape — yet the engine refused it at the door. Now
it counters: the vanishing goes up mid-stack (duration from a NUMBER
card riding the counteract command), the attacker's 1-in-4 hit roll
happens at resolution, the spell lingers after the exchange, and
ANTI-ANTI cannot pin it. WATERWALL — "Acts as counteraction to
FIREBALL" — now mirrors WALL OF FIRE's waterbolt-stopping role and
counts as a total stop. WALL OF FIRE itself joins the total-stop set
at rev 12 only: stored rev-10/11 games bounced after it and replay so.

While responding, tapping a number card holds it to ride the next
counter (unless a displayed Shieldstone makes the number itself the
counteraction, as before). The automatons learn the trick too: vanish
when the blow is heavy and the shields are spent, and never waste
ANTI-ANTI against an escape.
