/* Hallmark · genre: modern-minimal (bold/geometric variant) · macrostructure: Split Studio
 * theme: custom "Signal" — monochrome ink/paper + one acid-lime signal accent, hard 2px edges, hairline rules
 * nav: restrained flat bar (wordmark + 3 links + CTA, hairline bottom, no blur/pill — N9's silence doesn't fit a
 *      real multi-page agency site, so this keeps N9's restraint but adds the links usability requires)
 * footer: Ft2 Inline, extended with one real contact line (not a 4-column mega-footer)
 * craft: real wordmark reconstructed in CSS from the client's own logo (bold caps + boxed "LEADS"), no stock art
 * accent used at: focus rings, one CTA fill, the boxed logo mark, single "high-energy" numbers — never a flood
