+PHPUnit runs inside `@wp-playground/cli` (PHP-WASM + SQLite). The first run
+clones `tests/phpunit` from `wordpress-develop` into
+`wordpress-plugin/.wp-tests-lib/` (gitignored). Activation is handled by
+`playground/phpunit.blueprint.json`; config is in
+`wordpress-plugin/tests/wp-tests-config.php`. The test library's default install
+path (which forks a PHP subprocess via `system()`) is skipped with
+`WP_TESTS_SKIP_INSTALL=1` because Playground already provides a fresh SQLite DB
+per boot.
+
 Run `npm run lint` from the repo root to lint everything (ESLint + stylelint + markdownlint + Prettier).
