   Domeintekoop — design tokens
   Concept: the browser address bar IS the product. Ink-dark bookends (hero,
   footer, contact) frame warm paper-light content sections. Domain data is
   always set in JetBrains Mono (the registrar/DNS voice); headlines and
   persuasion copy are set in Fraunces (the human voice making the sale).
