superhuman.com is built on a pure-white canvas (rgb(255, 255, 255)).
The system uses rgb(212, 199, 255) as the singular interactive color.
Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside Super Sans VF as the primary typeface.
A layered elevation system (6 distinct shadows) building a clear front-to-back hierarchy.
Motion is minimal — a few targeted transitions, no decorative animation.

Type — the ladder, in the real face
5 roles · rendered live in the real Inter (captured woff2) · lines are editable, click any spec to copy
Use 16px border-radius on cards — consistent with the grid card corners
Maintain nav height at 42px — consistent vertical space for the navigation bar
Respect the 4px–32px spacing range — the design uses a wide scale for visual breathing room
Each card includes a top image — imagery is part of the card identity, not optional
Repeat the primary CTA across 2 banner sections — conversion paths are layered, not single
Don't
Don't use pure black (`#000000`) for text — the near-black adds warmth
Don't substitute with generic sans-serif or serif — the custom font carries the brand
Don't invent new shadow values — use only the extracted shadow levels
Don't apply pill radius on rectangular buttons or cards — it's reserved for specific interactive elements
Don't introduce additional saturated accent colors — the palette is intentionally controlled
Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence
Don't make the nav sticky — this design lets it scroll away to maximize content focus
Don't put a CTA button in the nav — this design uses links only at the top
