## Overview

The repository is named coreLangGen, but its README and sampled files do not describe a language-generation workflow. The only confirmed runtime behavior is admin PIN verification against a Firestore-stored hash, with an in-memory unlocked flag. The contents of index.html and any UI-to-verifier wiring were not sampled, so that connection is omitted.

Main entry points: [`auth-service.js`](https://github.com/dechp796/corelanggen/blob/main/auth-service.js) (PIN verifier), [`firebase-config.js`](https://github.com/dechp796/corelanggen/blob/main/firebase-config.js) (Firebase config)
