 * Context shared from `<VCBreadcrumb>` to its descendant parts.
 *
 * `themeVariant` (e.g. `{ size: 'sm' }`) propagates to **every** part so a
 * single `<VCBreadcrumb :theme-variant>` resizes the whole trail without
 * repeating the prop. `themeClass` propagates only to parts on the shared
 * `breadcrumb` root key (`<ol>` / link / page / ellipsis); the `<li>` and
 * separator carry their own keys and inherit `themeVariant` only.
 *
 * Optional — parts render bare when mounted outside `<VCBreadcrumb>` (unit
 * tests / ad-hoc composition).
