A research-journal aesthetic printed on warm stone — authoritative, editorial, almost achromatic. Pages live on warm ivory parchment (never pure white), with near-black slate as the dominant ink. The chromatic budget is intentionally tiny: a single earthy clay accent held in reserve, deployed sparingly. Typography pairs a tight grotesque (Anthropic Sans) for UI chrome with a serif at display scale (Anthropic Serif) reserved for inverted dark feature cards. Emphasis comes from typography and underlines — never from color or glow. Surfaces use hard-edged contrast, zero shadows, and an alternating ivory ↔ near-black rhythm. Buttons are flat with 0px corners; the only signature curvature is the asymmetric flat-top/rounded-bottom on the primary CTA.
