A searchable, scrollable browser that renders the same node data as the Graph
control as a list of cards grouped by category. Each card shows a live example of
the control on the left with its name and summary; tapping a card opens the
control's documentation. Reads the same synced GraphData value as graph and
uses only the nodes (edges are ignored).
Behavior
- A search field filters cards by name or category.
- Cards are grouped under category separators (Label headers): Controls, Display, Layout, System, Models.
- Tap a card to open its doc page; see Control Definition for the shared fields.
