Game

Game holds the full state of one Connect Four match. board is indexed board\[row]\[col]; row 0 is the BOTTOM row. It carries no ID field: the id belongs to the store, which hands it back on lookup and iteration.

games

games assigns the game ids. v1 kept its own nextID plus an idKey() that zero-padded to width 12, which stopped ordering the Render list past 10^12.

NewGame

NewGame creates a match between the caller (🔴) and opponent (🟡). Returns the new game id.
