/* Direction: The Instrument of Ownership.
   Prime's real differentiator is equity ownership, not culture claims — every
   competitor claims culture, none of them can hand you a stake. This system
   borrows the graphic register of the document that actually matters here: a
   share certificate / partnership instrument, not a marketing brochure and
   not the cream-parchment cliche. Ground is pale security-paper blue-grey
   (engraved-certificate paper, not old parchment), ink is a deep formal
   purple, brass is a sparing secondary accent for seals and rules — never
   gold-foil-everywhere. Petrona (formal serif) for display, Public Sans for
   body, real ruled borders standing in for an engraved certificate frame. */
