+.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.
+
+.EXAMPLE
+  ./scripts/e2e.ps1
+  ./scripts/e2e.ps1 -Test fixture_full_pipeline
