Nodes now support color coding

Every node card can now carry one of eight pastel tints: rose, pink, amber, sage, mint, sky, lavender, and clay. Use them to group a branch, mark the threads you want to return to, or keep two lines of thinking apart when they sit next to each other on the canvas.

There are three ways to set one, and all three open the same swatch grid. Press Cmd+B on the selected node, choose Color from the node right-click menu, or open the node drawer and pick from the palette there. The right-click path matters on a node with a settled answer below it, because that node never opens a drawer at all.

The tint fills the card body only. The border keeps carrying selection and generation status, so a colored node still reads as selected or still generating at a glance.

Color is not a content edit. It works on any node type, it is not refused by the lock that protects a node with answers beneath it, and Cmd+Z undoes it like any other change. Open a map and press Cmd+B on any node to try it.
