+# (Removed on 2026-07-23: the two overrides here, `plot/emcee_plotter` and
+# `plot/zeus_plotter`, were copied in from autofit_workspace's env_vars.yaml,
+# where the identical patterns still live and still match. Those scripts exist
+# only as autofit_workspace/scripts/plot/*.py and have never existed in
+# HowToFit, which contains only chapter_*/tutorial_*.py — so neither pattern
+# ever matched a file here.
+#
+# Do not copy override patterns between repos; a pattern that matches nothing
+# is silently inert, not an override. `overrides: []` is written explicitly
+# because env_config.py reads `.get("overrides", [])` — a bare `overrides:`
+# key would load as None and raise on iteration.)
