/**
 * Cache Coverage — a sidebar row that gathers the Pro features which
 * extend Page Cache beyond the default HTML-for-anonymous-visitors
 * behaviour (FBS-83633).
 *
 * A thin Free container: it owns no settings. Its panel renders the
 * existing coverage section (CacheExtras) with its three tabs —
 * What to cache / Feeds & API / Rules & bypass — each embedding the
 * Pro module that owns those settings. Being a Free container, the row
 * is never a locked dead-end; the individual tabs unlock in place.
 *
 * This lives as its own Cache sub-item (rather than stacked at the foot
 * of the Page Cache page) so the coverage features are reachable
 * directly from the sidebar.
 *
 * @package XSpeed
