   DESIGN TOKENS
   Palette chosen for this brief: deep charcoal-navy base (not pure black),
   soft indigo primary, teal secondary for metrics/highlights, warm amber
   used sparingly for the process signature. No previous portfolio palette
   was supplied, so these tokens are new — swap the hex values below to
   reuse an existing brand palette instead.
