   BRAND TOKENS
   ------------
   Everything visual on this site is driven by the custom properties in the
   :root block below. To match the palette to the application, replace the
   hex values in the "BRAND" group only — no other file needs to change.

   Mapping to the app:
     --ink-900 / --ink-800   dark chrome (sidebar, headers)
     --pulse                 primary system / data accent
     --amber                 primary call-to-action
     --mineral-*             page and card surfaces
