/*
 * Advertising Project — dashboard design system.
 *
 * A plain stylesheet rather than a build step: the dashboard is five pages of
 * CRUD and the blueprint's stack note is explicit about not putting a toolchain
 * between you and a working pairing flow.
 *
 * The class contract (card, pill, row, stat, dim, ghost, danger) is what the
 * views use, so the look can change without touching a single view.
