Document identicons, My games, and First to N Cards' bank-size behavior - Core Rules: new 'Identifying players' section for the per-player identicons. - New Finding a Game Again page for the My games list. - Categories and Delegation: clarify that the bank-size hard-block is mode-dependent (Classic Count/Deck Mode block on any shortfall, First to N Cards only blocks on zero eligible, otherwise runs smaller batches by design).
