+The badge is served from the site:
+[`docs/badge.svg`](https://github.com/commit-check/commit-check.com/blob/main/docs/badge.svg)
+in commit-check.com, a hand copy of the shields.io render below — same size,
+colors and flat style, with `badge-logo.svg` drawn as vectors — so the snippet

+
+The shields.io version is where that geometry comes from, and the one to use
+when you need a different `style=`:
+
+```text

 The `logo=` parameter is `badge-logo.svg`, base64-encoded, with `+` written as
 `%2b` (a bare `+` in a query string is a space). Shields.io only takes a
