# ============================================================
# LEGACY — original Google Colab notebook export, kept for reference only.
# Not part of the installable dense-evolution package (not in py-modules).
# Meant to be pasted/run as a Colab cell, not imported as a Python module —
# it has unconditional top-level `from google.colab import files` and
# `import ipywidgets`, so `import dash` fails outside Colab. The maintained,
# importable dashboard is dashboard_core.py + app_dashboard.py (Streamlit)
# at the repo root, which ported the same 8 panels from this file.
