UIContext.h file

UIContext: one UI document. The tree plus everything stored per node.

Owns the node storage and the rows beside it (layout inputs, text, style class, handlers, dirty flags, computed layout). A tree is built by running a function against a UI builder (UI.h). Running it again reconciles against the existing tree, so only real differences are created, moved, changed, or destroyed.

Single writer: the UI update.
