 ### Auto-regeneration
 
-A GitHub workflow (`.github/workflows/snapshot-badges.yml`) automatically regenerates badge assets when `src/badges.js` or `src/utils.js` changes on main:
+The CI workflow (`.github/workflows/ci.yml`) includes a `regenerate-badges` job that runs after tests pass:
 
 ```
-Push to main (badge code changed)
-  → Workflow runs snapshot-badges.js
+Push to main
+  → Tests run
+  → If tests pass, regenerate-badges job runs
   → If SVGs changed, commits and pushes
   → Vercel sees commit, redeploys demo
 ```
 
+Badge regeneration only happens on pushes to main (not PRs) and only after tests pass.
