+<#
+.SYNOPSIS
+  Run the same gates as the CI workflow, on this machine.
+
+.DESCRIPTION
+  Mirrors .github/workflows/ci.yml so a change can be checked before pushing:
+  formatting, clippy with warnings as errors, the unit and integration tests
+  (no browser, no network), the doc tests and a release build.
+
+  The browser end-to-end suite needs a real Chromium and is opt-in: pass -E2e
+  to add it after the other gates.

+<#
+.SYNOPSIS
+  Run the browser end-to-end suite against the local fixture page.
+
+.DESCRIPTION
+  The suite needs a real Chromium-based browser; it is ignored by default so
+  that "cargo test" stays usable without a browser. It drives a local static
+  fake of the ChatGPT page (tests/fixtures/chatgpt_mock.html): full pipeline,
+  streaming, conversation reuse, login, captcha, rate limit, error banner,
+  first-token timeout, missing selector, mid-stream rewrite and attachments.
