   fin.associates — component styles
   Implements the fin. associates Design System. Every value resolves to a token
   in tokens.css; nothing here is a literal colour, font or size.

   Brand rules enforced in this file:
   · Four colours only. Teal is the dot, hairlines, arcs and small tracked
     labels — never a background, never body copy. Primary actions are charcoal.
   · Serif (Cormorant Garamond) for display and headings; never letterspaced,
     never uppercase, never body copy.
   · Sans (Hanken Grotesk) 300 for body; uppercase is reserved for sans labels.
   · No rounded corners anywhere except the wordmark dot. No gradients except
     the warm-white image fade. No icons, swooshes or decoration.
