Replay viewer

The static replay bundle accepts the signed replay URL through #replay=<url> and can be opened after the game container exits. It loads completed replay frames without a live game connection. Version-4 recordings show historical hands; recordings with draft history also expose Draft and View decks controls. Switch players at the same pick or compare both side by side, then return to the saved Duel position. Earlier format-4 recordings remain playable without draft review; other replay formats are rejected.
