Responsive board and CC0 SVG pieces; local position save/restore; new-game action and keyboard-accessible squares.

The runtime directory contains the exact hosted files, including license notices and the local player bridge. Plain HTML/JavaScript games use runtime as their editable source.

To serve the independent game, mount runtime at /play/chess/ on any static HTTP server and visit /play/chess/index.html. The game never requires its upstream server. Game bridge notifications only operate when embedded by a same-origin parent.
