Where to find it in Lemwatch
/pulse/<scan-id> — shareable public URL for every scan.
How to act on findings
Fix any red (F) items first — they usually take minutes.
Amber (C/D) items are best-practice gaps.
Green (A/B) items are healthy — no action needed.
To re-scan after a fix, run Pulse again — new scan, new ID.
