"""
DEPRECATED — Weight data now comes exclusively from Health Connect.

Health Connect syncs daily via health_sync.py (launchd, 9 AM).
Your Nexus Pro scale → Health Connect app → Google Drive zip → health_sync.py → dashboard.

If you need to manually trigger a weight sync:
  python3 ~/clawd/health_sync.py

This file is kept as a fallback only. If used, it tags the entry
as 'manual' so it's clear it didn't come from the normal pipeline.
