* Shared node-tinted surface treatment so node cards and message bubbles match. A node's identity color is applied as a

* faint wash over the neutral card surface plus a node-colored outline — the more accessible alternative to a heavily

* saturated fill, since content keeps the surface/onSurface AA pairing while still reading as "this node".
