T8b949e/**

* A modifier that applies a glow animation to a node card when a packet is received.

*

* The glow blooms quickly using [MaterialTheme.motionScheme.fastSpatialSpec] and decays slowly using

* [MaterialTheme.motionScheme.slowSpatialSpec], creating an M3 Expressive motion effect.

*

* @param lastHeard The node's lastHeard timestamp. Changes trigger the glow animation.

* @param nodeColor The color used for the glow shadow (typically the node's assigned color).
