## Overview

2FRC is a small Streamlit app for applying a regex to two inputs and comparing the resulting matches. Its single runtime file collects URL, uploaded-file, or pasted-text inputs; fetches URL content, extracts and deduplicates matches, computes differences and overlap, and displays counts and tables. The README also claims report export, but no export implementation appears in the available source. The architecture is based on the single sampled source file.

Main entry points: [`main.py`](https://github.com/cchristion/2frc/blob/main/main.py) (Input interface)
