   Elisity Partner Lab Portal — CCC theme
   Single source of truth for the visual theme. Emulates the live Elisity
   CCC UI (insights-demo.idp01.elisity.io): MUI / Inter / navy rail / light
   canvas / teal accents / pill chips / stat-card row.

   Tokens below were extracted live from the CCC app (see task input/theme.json).
   To white-label: override the :root custom properties + swap public/brand/*.
