/* ==========================================================================
   MVC Inference Portal
   ==========================================================================

   Two token groups, deliberately separate:

   --brand-*    chrome: sidebar, accent, buttons. Swap these for your own
                brand and nothing else changes.
   --series-* / --ink-* / --grid-*
                chart tokens from the validated data-viz palette. These are
                NOT brand colours: they are chosen for contrast and CVD
                separation against the chart surface, and re-tinting them to
                match a brand breaks that. Leave them alone.

   Dark mode is declared twice on purpose: the media query follows the OS, the
   [data-theme] scope follows the in-page toggle, and the toggle must win in
   both directions.
