Conversion Pipeline

R13 XML file  →  useR13Parser.ts  →  useR14Generator.ts  →  R14 XML output
                 (parse to typed       (transform to R14       (download or
                  R13 objects)          XML structure)          copy to clipboard)

Security

• File size limit — 10 MB maximum
• Strict XML validation — Rejects non-XML and non-Joystick Gremlin files before parsing
• Filename sanitization — Blocks path traversal and special characters
• Content Security Policy — default-src 'self', connect-src 'none', frame-ancestors 'none'
• X-Content-Type-Options — nosniff
