/* Loople design 2.0 — demo layer.

 * one accent, one recipe for cards/buttons/navigation.  Product colours
 * (news category chips, feed labels) stay where they help the eye.
 *
 * Loaded after every service stylesheet; it only overrides tokens and the
 * shared components, never the content or the "voice" of the house.
