+## Static File Routes & Accessibility Scanner Support
+
+The CDP dev environment runs automated accessibility testing using HeadlessChrome. This scanner attempts to load icon resources (e.g., `aria.svg`, `header.svg`, `h1.svg`, etc.) to visualise accessibility features on the page. These icons are not part of the application itself but are used by the scanner's visualisation overlay.
+
+To prevent 400 errors in logs from these scanner requests, a catch-all route was added in `src/server/common/helpers/serve-static-files.js` that:
+
+- Intercepts all `/img/{param*}` requests
+- Returns a valid empty SVG with 200 OK status
+- Satisfies the accessibility scanner without cluttering logs with errors
+
+This ensures clean logs while maintaining compatibility with CDP platform accessibility monitoring tools.
+
+Test locally with:
+
+```bash
+curl -v http://localhost:3000/img/icons/aria.svg`
+```
