/**
 * Components — Image placeholder, empty state, loading skeleton
 * One treatment for a Catalog image that is absent or fails to load (Pool Type
 * and Series cards, the Model visualizer), the message a list shows when it has
 * nothing to offer, and the card grid shown while the config loads. The Option
 * info modal is portaled outside the wrapper, so its copy of the placeholder
 * lives in unscoped/wppb-modals.css.
