/* ============================================================================
   Preston-Check Customer Portal — visual system

   Reuses the brand tokens from web/landing/ and the layout primitives from
   web/admin/, with a customer-facing emphasis: the home page leads with a
   hero score badge instead of dense data tables, and the colour weighting
   leans more emerald (success) and less navy (operator-density). The
   audience here is a paying customer, not an operator.
