Resend — Style Reference

> Resend's marketing surfaces sit on a near-pure black canvas with off-white

text and a single signature color — the deep editorial-serif Domaine

Display headline mark — that gives an otherwise utilitarian developer-tool

brand its print-magazine confidence. The system pairs Domaine Display

(oversized 76px–96px serif, ss01/ss04/ss11 features on) with ABC Favorit

for body and Inter for UI. Surfaces rely on subtle 6–9% opacity gradient

glows, hairline 1px borders made from translucent white, and a strict

rounded-12px container vocabulary. There is no decorative chrome — just

type, code, and atmospheric depth.

    Do

  • Use `--color-primary` for the brand's primary interaction treatment.
  • Keep page surfaces anchored to `--color-canvas`.
  • Preserve every typography style's documented size, line height, and letter spacing.
  • Compare major implementation decisions against [the live Resend website](https://resend.com/).

    • Don't

  • Do not introduce colors outside the documented color token set.
  • Do not replace `--color-ink` with an arbitrary neutral.
  • Do not flatten documented component states or spacing relationships.
  • Do not treat this extracted snapshot as newer than the live source website.

    • Layout

    Use the documented spacing scale and component geometry as the implementation baseline. Validate responsive composition and current page rhythm against [the live source](https://resend.com/).
