Vercel Design System Tokens, Color Palette & Cursor SKILL.md

Visit vercel.com ↗

Aesthetic Archetype — Geist Architectural Grid & Swiss Precision Monochrome: Architectural #FAFAFA / #FFFFFF daylight grid with exposed 1px #EBEBEB structural hairlines, corner crosshair markers, ultra-tight -0.06em GeistSans display type, and #171717 monochrome CTAs. Use these deterministic CSS tokens and arbitrary Tailwind values in Cursor or Claude Code to replicate Vercel’s visual precision without generic AI purple-gradient slop.

## 1. Aesthetic Direction & Vibe
- **Archetype**: **Geist Architectural Grid & Swiss Precision Monochrome**
- **Semantic Vibe Tags**: `light`, `monochrome`, `grid`, `crosshairs`, `geist`, `vercel`, `developer`, `cloud`
- **Core Signature**: Architectural #FAFAFA / #FFFFFF daylight grid with exposed 1px #EBEBEB structural hairlines, corner crosshair markers, ultra-tight -0.06em GeistSans display type, and #171717 monochrome CTAs.
- **Atmosphere & Contrast Strategy**: Built on a light-mode foundation (`#FAFAFA` canvas -> `#FFFFFF` elevated surfaces) anchored by `#EBEBEB` structural borders, `GeistSans` display typography, and `#0070F3` primary accents.

### Real DOM Component Recipes
- **Interactive Buttons**:
  - **Button Variant 1 ("Sign Up")**: height `32px`, padding `0px 6px`, radius `6px` (`rounded-md`), bg `#171717` (`bg-[#171717]`), text `#FFFFFF` (`text-white`), border `none`, font `14px` / weight `500`
  - **Button Variant 2 ("Deploy now")**: height `40px`, padding `0px 12px`, radius `9999px` (`rounded-full`), bg `#171717` (`bg-[#171717]`), text `#FFFFFF` (`text-white`), border `none`, font `16px` / weight `500`

- **Cards & Containers**:
  - **Card Recipe 1 (685x580px)**: bg `#FAFAFA` (`bg-[#FAFAFA]`), border `none`, radius `6px` (`rounded-md`), padding `20px 20px`, shadow `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.08) 0px 0px 0px 1px, rgb(250, 250, 250) 0px 0px 0px 1px`
  - **Card Recipe 2 (685x580px)**: bg `transparent` (`bg-[transparent]`), border `1px solid #F2F2F2`, radius `4px` (`rounded`), padding `0px 0px`

### Motion & Transition Curves
- **Easing Curves (`transition-timing-function`)**: `cubic-bezier(0.4, 0, 0.2, 1)` (94x), `cubic-bezier(0, 0, 0.2, 1)` (8x), `linear` (2x), `cubic-bezier(0.23, 1, 0.32, 1)` (1x)
- **Transition Durations**: `0.1s` (79x), `0.2s` (8x), `0.15s` (7x), `0.3s` (6x)
- **Named Motion Tokens**: `--ease-in: cubic-bezier(.4, 0, 1, 1)`, `--ease-out: cubic-bezier(0, 0, .2, 1)`, `--ease-in-out: cubic-bezier(.4, 0, .2, 1)`, `--default-transition-duration: .15s`, `--default-transition-timing-function: cubic-bezier(.4, 0, .2, 1)`, `--duration: .56104s`

---

## 5. Anti-Patterns (Strictly Forbidden)

- **NEVER substitute generic uncalibrated gray backgrounds for Vercel’s exact `#FAFAFA` canvas and `#FFFFFF` surface pairing.**
- **NEVER replace `GeistSans` display typography or ignore its signature scale (`64px / -0.06em (w400)`).**
- **NEVER use thick opaque borders that clash with `#EBEBEB` (`1px solid #EBEBEB`).**
- **NEVER deviate from the signature button geometry (`6px / 9999px`) or introduce off-brand saturated gradients.**
- **NEVER use default browser monospace when rendering code or telemetry**—always pair with `GeistMono`.
