StyleSeed — Design Judgment Engine

> Teaches Claude Code design judgment, not just design data. 69 visual rules that make AI output look designed, not generated.

What It Teaches

• **Color discipline** — `#2A2A2A` as refined black, 5-level grayscale, one accent color maximum
• **Spatial rhythm** — alternating section heights, 2:1 number-to-unit ratios
• **Information hierarchy** — card/background separation, progressive density
• **Shadow & elevation** — 4% opacity ceiling, dark mode border substitution
• **Component variance** — never 4 identical KPI cards, stagger content types
• **Motion & feedback** — 200ms normal, spring for entrance, ease-out for exit

Quick Start

# Copy engine into your project
cp -r styleseed/engine/* your-project/

# Or just point Claude at the repo
# "Refer to https://github.com/bitjaru/styleseed — read engine/CLAUDE.md and DESIGN-LANGUAGE.md"
