/* Hallmark · pre-emit critique: P4 H4 E4 S4 R4 V4
 * macrostructure: single-section landing page (validation-stage — deliberately stripped of
 *   product mockups / feature claims per user request; not a full Marquee/multi-section build)
 * nav: minimal wordmark + single CTA (no logomark, per user request) · footer: Ft2-style
 *   inline single line
 * theme: studied-DNA (source: image, coasty.ai) · studied: yes
 * paper: oklch(9% 0.006 258) · ink: oklch(97% 0.004 258) · accent: none — true monochrome
 * display/body: General Sans · outlier: JetBrains Mono
 * axes: dark / grotesk-sans / neutral
 * enrichment: Tier A/B hand-built animated wireframe globe (SVG + CSS transform only,
 *   no video/WebGL) — explicit user request for a "slick, interconnected, animated" visual;
 *   continuous loop is an intentional exception to the usual no-infinite-loop default,
 *   gated behind prefers-reduced-motion: no-preference throughout
