promotion

Summary

A pawn has reached the last rank and the player chooses what it becomes.

Why it is drawn this way

The player chooses, every time. The current app promotes to a queen without asking. That is wrong in real positions: a knight can give a check a queen cannot, and a queen can stalemate where a rook wins.

Queen first. It is the right answer nearly always, so it is the first target. The other three cost one look.

It is a modal because the game cannot continue without the answer. The board underneath is drawn unchanged and inert, with the pawn already on its new square.

The card is bg-frame. In the dark palette --surface is a translucent tint and the board would show through the card.

No cancel. The pawn has moved. Taking the move back is Undo, after the choice.
