"component:create": "node scripts/generate-primitive.mjs"

# Then run:
npm run component:create Card
npm run component:create Badge
npm run component:create Modal
npm run component:create Alert
npm run component:create Spinner
npm run component:create Tooltip
npm run component:create Checkbox
npm run component:create Radio
