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
