  title: Browserless Scrape Then Screenshot
  summary: Extract structured elements from a page, then capture a screenshot of the same page as visual evidence.
  description: >-
    A data-plus-evidence pipeline. The workflow first runs /chrome/scrape to
    pull structured element data (text, HTML, attributes, and geometry) for a
    set of CSS selectors from the target URL, then captures a full-page
    screenshot of the same URL via /chrome/screenshot so the scraped data is
    paired with a visual snapshot of the page it came from. 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.
