  title: Browserless Performance Audit
  summary: Run a Lighthouse-style performance audit on a URL, then capture a screenshot of the audited page.
  description: >-
    A performance-with-evidence pipeline. The workflow first runs
    /chrome/performance to produce a Lighthouse-style audit (performance, best
    practices, and related budgets) for the target URL, then captures a
    full-page screenshot of the same URL via /chrome/screenshot so the numeric
    audit is paired with a visual snapshot of what was measured. Every step
    spells out its token query parameter and JSON request body inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
