1. Visual Theme & Atmosphere

Sanity's website is a developer-content platform rendered as a nocturnal command center -- dark, precise, and deeply structured. The entire experience sits on a near-black canvas (#0b0b0b) that reads less like a "dark mode toggle" and more like the natural state of a tool built for people who live in terminals. Where most CMS marketing pages reach for friendly pastels and soft illustration, Sanity leans into the gravity of its own product: structured content deserves a structured stage.

The signature typographic voice is waldenburgNormal -- a distinctive, slightly geometric sans-serif with tight negative letter-spacing (-0.32px to -4.48px at display sizes) that gives headlines a compressed, engineered quality. At 112px hero scale with -4.48px tracking, the type feels almost machined -- like precision-cut steel letterforms. This is paired with IBM Plex Mono for code and technical labels, creating a dual-register voice: editorial authority meets developer credibility.
