+## Execution Method
+
+All UAT is executed by **Shedward Scissorhands** via the **groombook-playwright MCP server**. No manual browser checks or scripted test suites are used for UAT.
+
+Shedward uses the `mcp__playwright-groombook__*` tool family to navigate, interact with, and verify the site. Each test case step is executed via MCP browser tools:
+
+- **"Navigate to [URL]"** → `browser_navigate`
+- **"Locate/Read [element]"** → `browser_snapshot` to inspect the accessibility tree
+- **"Click [element]"** → `browser_click` with element ref from snapshot
+- **"Verify [content]"** → `browser_snapshot` and check text matches
+- **"Check mobile responsiveness"** → `browser_resize` + `browser_snapshot`
+- **"Check console errors"** → `browser_console_messages`
+
+Shedward reads this playbook, executes each test case via MCP tools, captures evidence (snapshots/screenshots), and reports pass/fail per test case.
