Lesson 9/14 Prompt history, used as an AI development logbook

The full story of building an HTML chess game with an AI. It covers the key stages: designing the game, customising the look (background, pieces as JPGs), fixing bugs (the shape of the pieces, the script being rewritten), adding a player-versus-AI mode, and the final polish. A methodical approach, from experiment to refinement, including reading back the prompt history to improve the result. An AI development logbook.
