/* exploration.rocks — the ES3D marketing site, in the EXPLORATION SITES brand (es-draft-1.vercel.app).
 *
 * The parent brand's system (V:\ESOS DESIGN.md / styles.css): Graphite #1A101F type and dark panels,
 * Quartz #F4F1EC paper (never pure white), Vellum for alternating sections, Slate for body, Graticule
 * hairlines, and Ore #B8823A as a restrained accent that earns its appearances (≤2%). Two type voices
 * only — Source Serif 4 (light, 300) for display, Inter for everything else; no monospace. Structure from
 * whitespace, hierarchy and 1px rules; no glow, no gradient text, no bouncy motion.
 * Fonts are self-hosted (Source Serif 4 variable in /site/fonts, Inter in /fonts) — no third-party requests.
