K-UDA ENGINE • W3C DTCG DESIGN SYSTEM SPEC • ZERO RUNTIME JS

Kasuality Universal Design Artifact

Generate the infallible color contract between Designers, Developers, and Autonomous AI Agents. A standardized static bundle combining W3C Design Tokens, Native Self-Healing CSS (zero runtime JS dependencies), and APCA perceptual validation in a single source of truth.

APCA Perceptual Contrast Guarantee

Select your minimum contrast target (Lc) according to WCAG 3.0 APCA. The K-UDA engine automatically calculates the OKLCH lightness offset in real time.

Reference Surface Lightness (L) 94%

Interactive Split-Screen Playground (Self-Healing)

Observe how tokens and the Self-Healing CSS formula dynamically adapt across light and dark modes with zero manual recalculations.

Light Mode Lc +78 (Pass)

Dynamic Visual Contract

This text maintains perfect APCA contrast, computed directly from surface luminance.

Dark Mode (Native Inversion) Lc -76 (Pass)

Zero Manual Calculation

Under inverse polarity, contrast is mathematically assured by relative color syntax, preventing hallucinations.
