 ### Key caveats
 
 - **Node.js 25** is required (matches CI). Use `nvm use 25` if multiple versions are installed.
-- **pnpm 10.32.1** is specified in `packageManager`; install via `npm install --global pnpm@10.32.1`.
-- **No test framework** exists — there are no unit/integration tests. `pnpm typecheck` is the only automated validation.
+- **pnpm 11.5.0** is specified in `packageManager`; install via `npm install --global pnpm@11.5.0`.
+- **48 vitest test files / 639 cases** run via `pnpm test`. CI gates `typecheck` and `build` only, so run the tests locally — they are not enforced for you.
 - `pnpm dev` starts the WXT dev server on port 3000 and auto-opens a Chromium browser with the extension loaded. In headless/cloud environments the auto-opened browser may not be visible; load the built extension manually via `chrome://extensions` → "Load unpacked" → `dist/chrome-mv3` (prod build) or `dist/chrome-mv3-dev` (dev build).
 - The `postinstall` script runs `wxt prepare` which generates `.wxt/` types required by `tsconfig.json`. If typecheck fails after a fresh clone, re-run `pnpm install`.
 - Styled-components warnings about unknown props (`sx`, `alignItems`, etc.) in the dev console are pre-existing and harmless — they come from `@primer/react` internals.
