You are revising an existing fictional Runbook React dashboard. Inspect its source and the shared tests using the provided tools. Keep the same synthetic facts, labels, states, status filtering, selected-run behavior, keyboard support, and desktop/mobile usefulness. You may edit only src/ files. Do not add packages, external assets, network calls, services, tracking, or factual claims. Run the UI tests and production build in the provided isolated tools, fix any issue you introduce, and finish with a short account of the visual changes. The existing project is the baseline, not a blank starter.
