# Runs the bot without installing Edge, a driver or Python on the host.

# The image carries only what main.py actually reaches: selenium and numpy.
# pygetwindow, keyboard, matplotlib and pygame are used solely by the
# recording and visualisation scripts, which are developer tools rather than
# part of a run, and two of them are Windows-only.

# QUERY_SOURCE defaults to trends here so a container needs no Ollama account
# and no model download. Set it to llm and point OLLAMA_HOST at a reachable
# host to use a model instead.
