viewport

The edui Scene panel — a live 3D view of the world inside a dock tab.

A dedicated editor camera renders the scene (all !ui !EditorUI, so the panel never draws the editor UI it lives in) into a GPU render-target texture, which the viewport widget displays. The camera is reclaimed by name across hot-reloads, so editing the module never spawns a second camera or leaks the texture; the render target resizes to the panel's rect.

A framing toolbar orbits, tilts, zooms and resets the view. Requiring the module registers it into the edui shell (dock = "center"), so it sits in the middle of the default desktop arrangement between the Hierarchy and the Inspector.
