-- Per-game blocks of a disguised-robot opponent. A disguised robot is a shared pool
-- account reused across games under different per-game names, so it must never go into
-- `blocks` (that would make the same robot look blocked in the blocker's other games under
-- other names, leaking that it is a bot, and show its pool name instead of the one seen).
-- Each such block is recorded here against the specific game + seat, snapshotting the name
-- the player saw, so the blocked list shows it as a distinct personality and the in-game
-- card re-marks that one seat. The real robot account is never blocked, so the matchmaker
-- leaves robots free. Unblocking deletes the row.
