+## Playwright Full E2E
+
+Run the permanent grouped full-suite entrypoint with a hard max of 5 total workers:
+
+```sh
+npm run test:e2e:ci
+```
+
+Default worker allocation:
+
+```sh
+PLAYWRIGHT_PARALLEL_WORKERS_CHROMIUM=2
+PLAYWRIGHT_PARALLEL_WORKERS_FIREFOX=1
+PLAYWRIGHT_PARALLEL_WORKERS_WEBKIT=2
+```
+
+Optional overrides:
+
+```sh
+PLAYWRIGHT_PARALLEL_BASE_PORT=5191
+PLAYWRIGHT_PARALLEL_WORKERS_CHROMIUM=2
+PLAYWRIGHT_PARALLEL_WORKERS_FIREFOX=1
+PLAYWRIGHT_PARALLEL_WORKERS_WEBKIT=2
+```
+
+The runner fails fast if the combined worker count exceeds 5.
