# API keys for the practical sessions
# ----------------------------------------------------------------------------
# 1. Copy this file:            cp .env.example .env
# 2. Paste your real keys into  .env   (never into this file)
# 3. Check that .gitignore in this folder lists ".env" (it does)
#
# The notebooks load this file with python-dotenv. Your keys stay on your
# machine. If a key ever appears in a commit, on a screen share, or in a
# shared notebook, treat it as stolen: revoke it in the provider console
# and create a new one.

# instead of through OpenRouter.
