/* ===========================================================================
 * MODEL CENTER'S OWN DESIGN LAYER
 *
 * The public desk and Model Center are two products, and the design layer for
 * each was drawn separately: the desk is flat near-black (#08090F) with violet
 * held back for navigation, and Model Center sits on a blue-shifted ink
 * (#141824) with deep violet fields carrying the brand into the surface.
 *
 * They had been sharing the desk's palette, so the entitled product looked
 * like the free one. These overrides re-point the semantic surface tokens for
 * this route only — every component below keeps consuming the same token names
 * and inherits the layer without knowing about it.
