 * The single, canonical full-screen loading state for the whole app
 * (configure, dashboard, route guards). Keeping one component here means
 * navigating between guard → page never swaps loaders, so there is no flash.
 *
 * It also waits a short beat before appearing and then fades in: loads that
 * resolve quickly (the common case) finish before the delay and the user sees
 * nothing at all, instead of a logo that blinks for ~200ms.
