What Preline Theme Generator does

Wraps a self-contained, network-free Node.js generator that turns a brand color or hue into a complete Preline design-token theme (OKLCH color scale, gray scale, semantic surface/border/chart/map tokens, light+dark variants). Triggers on requests to create, preview, match, or validate a Preline theme, and explicitly excludes generic non-Preline CSS work or arbitrary command execution.
