Run

npm install
npm run dev

Test

npm test
npm run typecheck

Adding kit assets

Export shapes from the Figma kit as individual SVGs (blue variant), drop them in assets/graphics/, then:

npm run assets

Names come from filenames (cube-server.svg → "Cube Server"). Shapes can carry a customizable label (double-click a shape to edit it inline).

How color works

Every kit SVG uses the same closed 9-color palette. At render time those hexes are swapped for shades derived from the element's base color (hue-shifted, saturation/lightness-scaled in HSL). Any color works; the gray/blue/teal presets approximate the kit's original variants.

Storage

Documents are JSON in localStorage (blueprint:index, blueprint:doc:<id>), schemaVersion: 1.
