Tailwind CSS Design System Tokens, Color Palette & Cursor SKILL.md

Visit tailwindcss.com ↗

Aesthetic Archetype — Engineered CSS Grid Lines & Technical Blueprint Precision: Daylight #FFFFFF canvas overlaid with exposed 1px rgba(0,0,20,0.05) blueprint construction lines, monumental 96px Inter headlines (-0.05em), PlexMono utility classes, and #38BDF8 / #F6339A accents. Use these deterministic CSS tokens and arbitrary Tailwind values in Cursor or Claude Code to replicate Tailwind CSS’s visual precision without generic AI purple-gradient slop.

## 1. Aesthetic Direction & Vibe
- **Archetype**: **Engineered CSS Grid Lines & Technical Blueprint Precision**
- **Semantic Vibe Tags**: `light`, `css`, `design-system`, `grid-lines`, `blueprint`, `tailwind`, `devtools`, `plex-mono`
- **Core Signature**: Daylight #FFFFFF canvas overlaid with exposed 1px rgba(0,0,20,0.05) blueprint construction lines, monumental 96px Inter headlines (-0.05em), PlexMono utility classes, and #38BDF8 / #F6339A accents.
- **Atmosphere & Contrast Strategy**: Built on a light-mode foundation (`#FFFFFF` canvas -> `#F8FAFC` elevated surfaces) anchored by `rgba(0, 0, 20, 0.05)` structural borders, `Inter` display typography, and `#0EA5E9` primary accents.

## 5. Anti-Patterns (Strictly Forbidden)

- **NEVER substitute generic uncalibrated gray backgrounds for Tailwind CSS’s exact `#FFFFFF` canvas and `#F8FAFC` surface pairing.**
- **NEVER replace `Inter` display typography or ignore its signature scale (`96px / -0.05em (w400)`).**
- **NEVER use thick opaque borders that clash with `rgba(0, 0, 20, 0.05)` (`1px rgba(0,0,20,0.05)`).**
- **NEVER deviate from the signature button geometry (`16px / 9999px`) or introduce off-brand saturated gradients.**
- **NEVER use default browser monospace when rendering code or telemetry**—always pair with `IBM Plex Mono (plexMono)`.
