## Variant by background, not by mood

The `variant` prop names the MARK's tonal family. Pick the variant that contrasts with the background it sits on:

- `variant="light"` - peak-blue mark, for DARK backgrounds (navy bands, dark heroes, the dashboard's navy strip).
- `variant="dark"` - brand-blue mark, for LIGHT backgrounds (paper, paper-cool surfaces).
