 * design's right rail - a sticky column, no collapse toggle. Renders nothing when the page has no
 * headings.
 *
 * A client component (the scroll-spy and the sliding indicator need browser APIs). It receives the
 * already-computed, serialisable `toc` from the server `DocsPage`. For its jump links to resolve,
 * `DocsPage` injects matching anchor ids into the body's headings.
 *
 * @param props - see {@link DocsTocProps}.
 * @returns the minimap `<aside>`, or `null` when there are no headings.
