Suvanwita/TrustCart ? reverse-engineered prompt

Build me a local first Streamlit app that helps people tell whether product reviews seem trustworthy.

It should let me paste reviews, upload a CSV, or use sample data, then analyze the text for sentiment, emotion, suspicious review patterns, and the main product aspects people mention like battery, delivery, quality, and price. I want it to calculate a clear trust score and give a simple final recommendation like Strong Buy, Buy with Caution, Mixed, or Avoid.

Please make it work without paid APIs, and if model downloads fail or the machine is limited, it should still run with sensible fallback logic instead of breaking. I also want a clean report page that shows the pros, cons, suspicious signs, who should buy, who should avoid, and lets me export the results as JSON and CSV. If you need to look up the current docs for any libraries, go ahead and do that.
