   Tokens: Deep Ink #0E2436 | Warm Bone #F5F1E9 | Stone Grey #6B7280
           Rare Brass #B08D57 (sparingly: CTAs, set-point, "territory",
           quote marks). Never a dominant fill.
   Type:   Marcellus (display/headlines) | Hanken Grotesk (body/UI)
   Rhythm: bone-dominant; ink as punctuation only (Exclusivity peak,
           Final CTA, Footer).
   CSS is MOBILE-FIRST: base rules are the phone layout, the
   @media (min-width: 720px) block layers on the desktop layout.
   (720px is the threshold from the source design; tablet/desktop
   share the wide layout, auto-fit grids collapse columns on their own.)
