joyrl-book

Plan and implement interactive chapter or playground pages for this Docusaurus repo. Use when Codex needs to port AI-generated JSX into JoyRL Book, add a standalone interactive route under `src/pages/`, wire a chapter into interactive mode, or extend the current left-reading/right-playground interaction pattern.

Stage the relevant git changes and create a commit using this repo's emoji-prefixed conventional commit format. Use when the user asks Codex to commit changes, stage and commit selected files, or draft a concise Chinese commit message from the current diff.
