How it works
- Fetches your start page and extracts its same-origin links (up to 60)
- Checks each link with HEAD (GET fallback) — 6 at a time, 8s timeout each
- Reports broken (4xx/5xx), errors (DNS/timeout) and redirects separately
- Private, loopback and reserved hosts are never touched
Same-origin links only in this version. Nothing is stored.
