Nested routes render parent layouts around the child. Input: line 1 — JSON object mapping path → component for nested levels (e.g. {"/": "Root", "/shop": "ShopLayout", "/shop/items": "ItemList"}); line 2 — the URL. Print the render chain for every prefix that exists, outermost first, joined by >.

Input: two lines. Output: chain like Root > ShopLayout > ItemList.
