- Replaces unsafe innerHTML usage with document.createElement and appendChild in the table drawing fallback.
- Adds a unit test `tests/qrcode_table_fallback.test.mjs` to verify the table generation logic using JSDOM.
- Addresses a potential security vulnerability where HTML injection could occur (though unlikely in this specific context, it is best practice).
- Updates package.json to include jsdom in devDependencies (if not already present).
