Bednar Chess Replay

Bednar Chess Replay enhances same-origin Embed Chessboard/pgn4web frames on individual posts and pages. Install and activate Embed Chessboard separately. This is an independent add-on, not a replacement chess engine or an official pgn4web product.

• Expand the entire player with the browser Fullscreen API. Exit using the button or Escape.
• When browser fullscreen is unavailable, a clearly labelled viewport overlay is used where the page layout permits it.
• Keep the current game, move, variations and appearance while changing display modes.
• Separate Page width mode respects content columns and uses a top-layer panel when needed.
• Five appearances: Original, Wood, Green, Blue and Night. The choice is saved in localStorage on your site.
• Responsive square board, move list and labelled replay controls.
• Readable, keyboard-accessible engine alerts, including help for misconfigured live broadcasts. Original pgn4web diagnostics remain available.
• English interface and bundled Czech translation.

The add-on does not create upload endpoints, fetch remote PGN, modify game data, add analytics, contact external services or impose paid/trial restrictions. Embed Chessboard owns its existing PGN loading and configuration. All assets supplied by this add-on are local and human-readable; no build step is needed.

This plugin was previously distributed privately as SSZK responsive chessboard. Its existing CSS classes, script handle and theme preference key remain compatible. Deactivate the old add-on before activating this one. If your theme already supplies the old script handle, remove that duplicate integration before using this add-on.
