   Calibrated — "Instrument Panel"
   A dark blue-slate calibration instrument. The page opens with the shape of
   its honesty (a reliability sparkline + Brier), not a pick. The signature is a
   signed-log-odds diverging driver chart on a gold zero-axis.
   Tokens are CSS custom properties; gold is STRUCTURAL only (never small text).
