  Convert PPTX files into real, editable HTML/CSS markup instead of SVG—improves searchability, customization, and accessibility.
• Preserve PDF Copy Protection in HTML Output:
  Securely honor content protection by rendering PDFs to HTML with the inert attribute, preventing copy-paste functionality.
