BrainTreeModel is the single source of truth for what is in the scene: each renderable owns a AbstractTreeItem-derived row and exposes its visibility, transform, colour and alpha through the standard Qt item-data roles. The tree is structured by subject → modality → instance so a multi-subject study can be browsed and toggled from a single side-panel.

BrainView listens to dataChanged / rowsInserted on the model, rebuilds its scene-map entries on the fly and pushes the resulting render-state into the QRhi pipeline — no other controller needs to know that a surface was added or hidden.
