Start by running the listed lychee command and reviewing the affected files: docs/contributing/rotating_github_tokens.md, the style-guide READMEs, docs/talks.md, etc/python/README.md, and FAQ.md. Check each reported URL manually, then update or remove links that are genuinely obsolete; done means the confirmed broken links are resolved or explicitly accounted for.
