8/* The 五子棋 everyone has played in an app: a wooden board with its star points and A–O / 1–15 along the edge, glossy
9 black and white stones dropping onto it, the last move dotted red, the winning five lit, a player card on each side
10 (the one to move glows), and a banner at the end. Replays get a play bar; a live table takes clicks (?live). */
