- Viewer renders through the comp's 3D view (RenderOpts.view; FrameKey hashes
the view camera), shows the view name, and the bottom-bar 3D View dropdown
(automation id viewer.view3d) switches Active Camera/Front/…/Custom View 3.
- Orbit / Pan / Dolly tools drag the current view (camera layer in Active
Camera, merged into one undo step; view cameras otherwise).
- Handles, gizmo and picking go through the view camera; 3D layers move in
the view plane at their depth.
- Camera frustum + POI and light position/direction wireframes
(viewer.camera.<id>, viewer.light.<id>).
- Camera Settings / Light Settings dialogs open from New Camera/Light,
Camera/Light Settings and Layer Settings; OK runs the engine commands.
- Timeline: POI only for two-node cameras/auto-oriented lights; "Z Rotation"
label on 3D layers.
- Headless egui_kittest tests (UI wiring + opt-in wgpu snapshots); fix the
remaining workspace clippy lints.
