/* nirs4all-ui — Dataset Builder default stylesheet.
 *
 * Ships a working, product-quality look for the `DatasetBuilder` wizard out of
 * the box. Reuses the shared nirs4all theme tokens (assets/theme.css) when the
 * host loads it, but every token has a literal fallback so this file stands
 * alone. Role colours are the stable contract: X=blue, Y=red, metadata=green,
 * ID=amber, partition=slate, replicate=violet, group=cyan.
 *
 * Import: `import "nirs4all-ui/assets/datasetBuilder.css"`.
