/* Punctuality dashboard.

   Colour roles come from the validated data-viz palette: one blue for the
   single-series charts, and the fixed status colours for the punctuality mix.
   Status yellow sits below 3:1 on the light surface by design, so every
   segment of the mix bar carries a visible label rather than relying on its
   colour -- and each chart can be switched to a table. */
