/* Configurator styling — follows drift-brand guidelines:
 *
 *   - System-UI typography, three weights only (300 light, 600 bold, 700 heavy)
 *   - Light gray surface (#e2e2e2), white panels, ink borders
 *   - NO rounded corners, NO blurry shadows, NO gradients
 *   - Shadows always hard var(--ink), never #000
 *   - Toy affordance: raise on hover, slam on click
 *   - Spinner: static square, edges light up in brand colors (no rotation)
 *
 * See brand/BRAND.md for the full specification.
