Brandon ThomasandClaude Opus 5.5 dec091e575 M7.5: advanced 3D renderer
Advanced 3D comps render their 3D runs as one scene of world-space triangles: model and
primitive layers (meshes, skinning, animation clips by layer time), extruded text/shape
layers, and textured cards for every other layer with their Material Options. Shading is
physically based in linear light: Cook-Torrance GGX + Lambert for parallel/spot/point lights
(AE falloff and cone), ambient lights, image-based light from an Environment light's layer
(equirectangular; cosine irradiance map + roughness mip chain + split-sum BRDF fit), and
PCF shadow maps (spot/parallel/point cube faces). 2x2 SSAA, depth of field as a gather blur
by circle of confusion, back to the working encoding.

The software rasteriser (depth buffer, top-left rule, perspective-correct, opaque visibility
then sorted transparent blending) is the reference and CI path; effectcraft-gpu implements
Accelerator::raster_3d with a wgpu render pipeline (advanced3d.wgsl) and matches it within
tolerance. Environment layers are hidden from both renderers.

Brandon ThomasandClaude Opus 5.5 76ac3f74f7 M7.1: Classic 3D renderer, cameras, lights, 3D views and camera-tool commands
- render/three_d: camera eval (one/two-node, DOF), default 50mm comp camera,
  orthographic Front/Left/Top/Back/Right/Bottom + perspective Custom Views,
  orbit/pan/dolly rig math; lights (parallel/spot/point/ambient, falloff,
  cone feather) and material shading; per-pixel depth-sorted compositor for
  3D runs (exact intersections, perspective-correct sampling, blend modes,
  track mattes, motion blur), ray-cast planar shadows with transmission and
  diffusion, per-layer DOF blur. RenderOpts.view camera override.
- project: camera iris/highlight props, aperture per comp width, light
  orientation/rotations, two-node auto-orient defaults.
- engine: layer.newCamera/newLight with presets & settings,
  layer.cameraSettings/lightSettings (Layer Settings dispatches),
  view.set3DView + View > Switch 3D View items (F10/F11/F12), last/reset view,
  camera.orbit/pan/dolly, view.get3D; EditorState.views3d.
- demo: "3D Showcase" comp (camera move, key spot + ambient fill, shadows,
  DOF, intersecting planes, gridded floor).
- tests: projection, depth order, intersections, lighting, shadows, DOF,
  views, rig math; command undo/redo. Fix a few pre-existing clippy lints.
