Hey there, thanks for sharing all the details and welcome to the Streamlit community! 
The “Error: Your account has exceeded the fair-use limits and was blocked by the system. Code: 403” means your Streamlit Community Cloud account was automatically blocked for exceeding resource or fair-use limits. This can happen due to high memory/CPU/storage usage, rapid deployment attempts, or sometimes a false positive by the system—even if your app didn’t get much traffic or failed to deploy.
To resolve this, you need to open a support ticket and include your GitHub username. The Streamlit team will review your case and help unblock your account if appropriate. You can find the step-by-step process in the official docs: Login attempt to Streamlit Community Cloud fails with error 403. If you’d like help optimizing your app to avoid future blocks, please share a minimum reproducible example or your repo link (which you already did—thanks!). Community members, feel free to jump in with your experiences or tips!
