   Palette drawn from the mark: deep navy pillar, gold capital.
   Typographic pairing: Playfair Display (authority, legal weight)
   + Inter (clarity, modern compliance) + IBM Plex Mono (dates/figures).
   Signature element: the "column rule" — a thin fluted-column
   divider echoing the logo's pillar, used to break sections instead
   of generic gradient dividers.
