The badge
A number a site can wear
The badge is a small SVG served at /badge/{domain}. It always shows the domain's latest scores, links back to the full report, and exists only for domains that have actually been scanned. A domain with no report gets a 404, never a placeholder: a number this product did not measure is not a number it will serve.
No scans exist yet, so there is no badge to show: the examples on this page render from real reports and nothing else. Scan a site and come back.
Embedding it
Every report page carries copy-ready HTML and markdown snippets under "Show the score", with a picker for the variant, the metric and the ground. The snippet links the badge to the report, which is where a curious visitor should land.
The image is served with an hour of caching, so a rescan shows up on the badge within the hour. The parameters are variant (full, compact, metric), metric (gap, human, agent, composite) and theme (light, dark); anything unrecognised falls back to the default badge rather than erroring, so a pasted URL keeps working.
