   prototypes/fe/v5/app/colors_and_type.css), copied as a pattern under
   ADR-0001 (zero runtime dependency on counsel, nothing written back to it).

   TODO(brand): every --verity-brand-* token below is a PLACEHOLDER neutral
   professional palette. Replace with the real askverity brand system once the
   operator sets a visual direction (FE-DESIGN section 15: "Design system and
   visual direction ... operator owns brand direction for askverity").
