/* ===========================================================================
   viralgen-53 — built to the OBF brand kits in "Layouts and brand instructions".

   Colour is specified as ROLES, never as brand names, exactly as
   patterns/README.md requires. Each brand maps the roles to its own palette in
   the [data-brand] blocks below; every component below refers only to roles.

   Two rules from the kits that are easy to get wrong and are enforced here:

   1. Mira's brass (#c3a544) is a FILL colour. It measures 2.39:1 as text on
      white — unreadable. Text set in brass uses --brand-ink (#7a621b, 5.85:1).
      That is why --accent-fill and --accent-foreground are separate tokens
      rather than one accent.
   2. Text ON a brand fill is not always white. RedFish and OBF take white;
      Mira takes navy (#1f2e48 on brass = 5.70:1). Hence --accent-on.

   No dark mode. The RedFish kit states the palette has no dark variant and one
   must not be invented silently.
