;;
;; valley-blocks (game2) — the p2p tetris. Unlike every other game, each seat
;; simulates its own board from the shared round seed and broadcasts "bs" board
;; states; the host only referees the verdict. This client runs the ported
;; engine for real: on "st" it seeds a board, decides one placement per piece
;; (your onPiece policy, or the stock Dellacherie autopilot), and executes it
;; input-by-input at a human-ish pace — a bot that instantly hard-dropped every
;; piece would be unbeatable in a score race, so pacing is the default and
;; configurable, never absent.
;;
;; Views handed to onPiece are field-identical to the gym's (seat, over, score,
;; lines, level, piece, hold, canHold, candidates, rivals, mode, target — in
;; that order), so a policy trained offline plugs in unchanged. With `host` set
;; the client can claim an empty room and referee rounds itself. The old
;; graceful-loser behavior (announce a topped-out board, never steal a win)
;; survives behind `forfeit: true`.
;;
;; Client side: send "hi"/"bs"/"lv" — receive "ro","st","bs","ov","lo","sn".
