URL hygiene report

HowToFit

Broken live URLs

The weekly URL audit found 2 broken URL(s) in HowToFit that are not in .url_check_allowlist.txt.

If these are genuinely-broken-but-acceptable (paywalled, dead-external, etc.), append them to .url_check_allowlist.txt to grandfather them. Otherwise fix the references in-repo.
