"""firebase_website — Bot → Firestore sync using the Admin SDK.

Requires GOOGLE_APPLICATION_CREDENTIALS env var pointing to a service-account JSON.

This package is loaded as a Discord extension purely for lifecycle hooks
(setup / teardown).  It does not register a Cog — it starts a background
SysInfoSync task instead.

Usage from main.py:
    await bot.load_extension("firebase_website")
