Path to the saved HTML file, e.g. product1.html. This is what you need to analyze. Don't proceed if it's not provided.
Path to output file, e.g. product1.json. When provided, this is where you will save the structured analysis.
Path to data-type spec.json. When provided, guides extraction using schema field names, descriptions, and examples.
Whether to strictly extract only the fields listed in the schema, if the schema was provided. When asked for strict extraction, extract only schema fields — no extras.
