Yongbeenm/Expert_sunflower-deploy ? reverse-engineered prompt

Build me a bilingual sunflower disease diagnosis app for farmers and agronomists. I want a simple web app where someone can enter or choose the symptoms they see in the field, then get a likely diagnosis, supporting signs, and clear guidance in both English and Khmer.

Please make the backend with a JSON API and a PostgreSQL database, and make the frontend a clean single page app that talks to the backend only through the API. Include the basic setup so I can run it locally with Docker, and make sure the database can be seeded with starter data. If there are admin or knowledge base features needed to manage symptoms and disease rules, include those too in a straightforward way.

Keep the UI easy to use on mobile, and make the whole thing feel polished and production ready. If you need to check current docs for any tools or libraries, go ahead and do that.
