Clean addition overall: a dedicated .lycheeignore with clear inline guidance reduces noisy link-check failures and is easy to maintain. The only issue is the GitHub avatar ignore pattern being overly narrow; widening it will make the ignore robust to common query-string variants and avoid future CI regressions.

cc @glenn-jocher friendly ping for review for fixing author URL problem.

Merged — huge thanks @onuralpszr for this thoughtful improvement, and appreciation to @glenn-jocher for the support and collaboration on it. 🙌

As Benjamin Franklin put it, “An ounce of prevention is worth a pound of cure.” This PR nails that idea: adding .lycheeignore prevents noisy, non-actionable 404s from derailing docs CI, keeps link-check reports clean, and gives the team a clear, maintainable place to handle recurring external link issues over time.

Thanks again for making the docs pipeline more reliable for everyone contributing to Ultralytics.
