+- After every frontend change, verify the results using an ephemeral Playwright run.
+  - For ad hoc verification in this repo, do not default to `npx playwright test` with a temp spec outside the repo.
+  - Prefer a repo-local ephemeral Node script under `artifacts_verify/` that imports `playwright` with `require('playwright')` and drives the browser directly.
+  - If using the Playwright test runner, use the repo-local CLI at `node_modules\.bin\playwright.cmd` and keep the spec inside the repo so local `node_modules` resolution works.
+  - Do not mix the global Playwright CLI with the repo-local `@playwright/test` package.
+  - When browser verification needs the app running, launch the app against a temporary copy of `src\RolemasterDb.App\rolemaster.db` so verification does not mutate the canonical DB.
