Your Streamlit script, read properly

Paste the app.py that grew. The browser reads every st. call, every widget key, every session_state access and every cache decorator, and tells you what Streamlit is going to break on — for free, before you sign in. Then pick a lane.

Both examples ship with a saved model run for every lane, so you can see all six outputs without signing in and without spending a credit.

Anything else worth knowing

A handoff from another lane also lands here, carrying that lane's conclusions forward.
