/* agent-eval demo: the look of the framework's Streamlit dashboard, in plain CSS.
   Chart colours are the dashboard's own (agent_eval/dashboard/charts.py,
   Palette): one blue for data and improvements, red for regressions, grey
   for no call. Never green/red. Small text uses the darker -text variants of
   the red and blue so it clears 4.5:1 on white. */
