+# Widget visual results
+
+This directory is intentionally empty until validation runs against the user-provided WordPress site.
+
+The browser run must create the screenshot paths declared by `tests/fixtures/widget-golden-v1.json` and a `manifest.json` using schema `aksrt.widget-visual-results.v1`. Validate completed results with:
+
+```text
+php tools/validate-widget-golden.php --require-results
+```
+
+The validator requires all 222 viewport/theme screenshots, every declared interaction state, zero console errors, zero unexpected network failures, zero critical/serious accessibility findings, reduced-motion verification, a maximum 2 px component-boundary delta, and a maximum 1.5% pixel difference.
