HTML to PDF

Render a URL or raw HTML string to PDF. Returns pdf_base64 (base64 PDF — decode to get raw bytes) and page_count. Provide url OR html — never both. Supports format (A4/Letter/Legal), landscape boolean, and margin settings (top/bottom/left/right in CSS units). Use for invoices, reports, or printable document generation.
