The GraphQL queries follow the agreed API contract. I verified that all 11 existing tests, linting and the production build pass.

A few changes before merging:

• Detail-view focus: The focus effect runs when selectedId changes, before the async response arrives and the heading exists. Move focus once the details have rendered, and add a test for this.
• Missing game: Handle game: null separately from request errors, with a message saying the game was not found.
• Documentation: Add the AI usage declaration to docs/frontend.md, as agreed in the plan.

The formatting check failed locally because of Windows line endings. We’ll handle a shared line-ending rule in a separate issue, so no change is needed for that in this PR.

The tests currently use mocked GraphQL responses. Once the backend is available, we’ll also need to verify that the frontend works with the real API and database.

Verified commit eba6445: all three previous review points are addressed. The detail heading receives focus after loading, missing games have a separate message, and the AI usage declaration is present. All 13 tests, ESLint and the production build pass.

One small item remains before approval: npm run format:check fails for src/App.tsx and src/App.test.tsx. I checked a copy using LF line endings, so this is formatting of the new code, not the shared line-ending issue tracked in #5.

Please run npm run format, confirm npm run format:check passes, and commit/push the formatting changes. No further functional changes requested.

Reviewed commit 402be7b. The remaining formatting issues are fixed: npm run format:check passes, and all 13 tests pass. The latest commit only changes formatting.

The earlier feedback on detail-view focus, missing-game handling and the AI usage declaration has been addressed. No further blocking findings. Approved.

Integration with the real GraphQL backend and database remains part of the planned integration checks before delivery.
