keep_alive.py

# ============================================================
# PhishGuard AI - keep_alive.py
# Keeps your Render.com server awake 24/7.
#
# From architecture doc 5.3:
#   Render free tier sleeps after 15 min of inactivity.
#   This pings GET /health every 14 min to prevent that.
#
# WHERE TO RUN:
#   - On a second laptop / old computer
#   - On your phone using Termux (free Android app)
#   - On a friend's computer
#   - On your own laptop in a separate terminal (less ideal)
#
# HOW TO RUN:
#   python keep_alive.py
#   (keep this terminal window open — never close it)
# ============================================================
