/* ==========================================================================
   server3 control panel — stylesheet

   Colour comes from the validated reference data-viz palette: categorical
   slots 1–3 (blue / orange / aqua), the fixed status palette, and the chart
   chrome + ink roles. Slots 1–3 are the documented all-pairs-safe subset, so
   every chart here caps at three series by construction.

   Dark mode is *selected*, not an inversion: each role has its own step
   chosen for the dark surface. Values are declared in three scopes so the
   toggle wins in both directions over the OS preference.
