Rebuild "Prism" as a separate, playable browser game using JavaScript, HTML, Canvas 2D, Browser. Preserve the observed gameplay: A 24-level optics puzzle. Place and rotate mirrors, glass, prisms and filters to route the correct light colors to every target; include deterministic solvable boards, hints, undo/reset, level selection and saved progress. Use Claude Opus 5.5 only as the documented creator attribution; some games call DeepSeek at runtime, which is separate from the build-model claim. Use a scripted/demo fallback when the optional model or network is unavailable. Implement the source-observed start state, controls, rules, game-state transitions, progression and completion/failure feedback. Keep it self-contained and verify the behavior against https://github.com/swan4er/opus-100-projects/blob/main/021-prism-puzzle/README.md and https://github.com/swan4er/opus-100-projects/blob/main/021-prism-puzzle/index.html.
