<#
.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
#>
param(
    [string]$Test = ''
