/**
 * ThumbnailCard
 *
 * One card in the visual component sidebar grid: a live preview above a
 * centered, human-readable name.
 *
 * To keep opening a category feeling instant, the expensive live <Render> is
 * NOT mounted on the first commit unless a preview is already cached.
 * Otherwise, a lightweight skeleton paints immediately and the real preview
 * is scheduled on idle time, then swapped in. The preview is wrapped in an
 * error boundary so a single misbehaving component degrades to a placeholder
 * rather than taking down the drawer.
 *
 * Seeding `ready` from the cache matters beyond the first paint: Puck's own
 * <Drawer>/<Drawer.Item> primitives remount on unrelated editor state changes
 * (e.g. typing in any field), which remounts every ThumbnailCard too. Without
 * the cache check, `ready` would reset to false on every one of those
 * remounts, flashing the skeleton back in even for previews already rendered.
