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

Aesthetic Archetype — Modern Link Attribution & Crisp Satoshi/Geist Minimalist: Airy #FAFAFA canvas with #FFFFFF analytics cards, #E5E5E5 1px borders, geometric Satoshi 48px display headings, GeistMono shortlinks, and high-contrast #000000 8px-radius primary buttons. Use these deterministic CSS tokens and arbitrary Tailwind values in Cursor or Claude Code to replicate Dub’s visual precision without generic AI purple-gradient slop.

## 1. Aesthetic Direction & Vibe
- **Archetype**: **Modern Link Attribution & Crisp Satoshi/Geist Minimalist**
- **Semantic Vibe Tags**: `light`, `analytics`, `marketing`, `saas`, `dub`, `satoshi`, `geist-mono`, `minimalist`
- **Core Signature**: Airy #FAFAFA canvas with #FFFFFF analytics cards, #E5E5E5 1px borders, geometric Satoshi 48px display headings, GeistMono shortlinks, and high-contrast #000000 8px-radius primary buttons.
- **Atmosphere & Contrast Strategy**: Built on a light-mode foundation (`#FAFAFA` canvas -> `#FFFFFF` elevated surfaces) anchored by `#E5E5E5` structural borders, `Satoshi` display typography, and `#000000` primary accents.

- **Cards & Containers**:
  - **Card Recipe 1 (908x580px)**: bg `transparent` (`bg-[transparent]`), border `1px solid #E5E5E5`, radius `20px 20px 0px 0px` (`rounded-3xl`), padding `12px 12px`
  - **Card Recipe 2 (882x567px)**: bg `#FFFFFF` (`bg-white`), border `1px solid #D4D4D4`, radius `12px 12px 0px 0px` (`rounded-xl`), padding `0px 0px`
  - **Card Recipe 3 (287x270px)**: bg `transparent` (`bg-[transparent]`), border `1px solid #E5E5E5`, radius `8px` (`rounded-lg`), padding `0px 0px`

### Motion & Transition Curves
- **Easing Curves (`transition-timing-function`)**: `cubic-bezier(0.4, 0, 0.2, 1)` (76x)
- **Transition Durations**: `0.15s` (40x), `0.3s` (13x), `0.2s` (12x), `0.5s` (9x)

## 5. Anti-Patterns (Strictly Forbidden)

- **NEVER substitute generic uncalibrated gray backgrounds for Dub’s exact `#FAFAFA` canvas and `#FFFFFF` surface pairing.**
- **NEVER replace `Satoshi` display typography or ignore its signature scale (`48px / 1.15 (w500)`).**
- **NEVER use thick opaque borders that clash with `#E5E5E5` (`1px solid #E5E5E5`).**
- **NEVER deviate from the signature button geometry (`8px`) or introduce off-brand saturated gradients.**
- **NEVER use default browser monospace when rendering code or telemetry**—always pair with `GeistMono`.
