Find and report a novel error on the public runx docs/site

Find one real, reproducible, previously-unposted error on the public runx docs/site (broken page, 500, dead link, wrong or contradictory instruction) and supply the corrected text or patch. The site repo is not public, so the deliverable is the report plus the exact fix, not a PR. The defect must be novel: already-known defects are not eligible. Check the ledger and open bounties first.

Deliverable:A reproduction (exact URL, observed failure, HTTP status or captured response) and a specific fix (corrected copy or a diff) for one novel public docs/site defect.
