GetYourWish/vegan-additives-checker ? reverse-engineered prompt

Build me a simple browser app that lets someone paste a product ingredient list and instantly see whether it looks vegan friendly or not.

It should work completely offline in one HTML file, with no tracking or ads, and it should be easy to open in any browser. Please make it recognize common animal derived additives, E numbers, and sneaky ingredients that are not obvious, while avoiding false alarms for things like coconut milk. I want clear color coded results for definite animal ingredients, hidden animal ingredients, grey area ingredients that need checking, trace warnings, and a clean result when nothing suspicious is found.

Please include English, French, and Arabic, with Arabic laid out right to left, plus a few theme choices like dark and light. Make it accessible with keyboard support and screen reader friendly labels. It would also be great if users can copy the result or share it from a phone, and see small toast messages for actions. If you need to check current browser support details online, go ahead and look them up.
