Importing a glTF / OBJ model opened Interpret Footage: the probe
reports straight alpha and the file has no alpha label, so with
Settings ▸ Import ▸ Interpret Unlabeled Alpha As at Ask User (the
default) the model was listed as unlabeled. Only image footage
(stills, sequences, video) can have unlabeled alpha; a model renders
its own, and audio and data have none.
Test: importing_a_model_does_not_ask_about_alpha (engine).

The host test writes a binary glTF cube (built in the test), imports it
with the real media layer, makes New Comp from Selection and renders
with no accelerator (the CPU path an Intel HD Graphics 5500 most likely
gets): the comp is Advanced 3D and the red cube covers part of the
frame. Before the fix the comp stayed Classic 3D and drew nothing. The
engine test checks the switch, its single undo step, the toasts, that a
second model doesn't switch again, and primitives.

Comps expose controls (properties typed as text/color/slider/checkbox/point/angle/dropdown,
Media Replacement, groups, comments); precomp layers get an Essential Properties group whose
edits override per instance (Push to Comp / Revert); templates export/import as an open ZIP
(manifest.json + project subset + media + poster). Stretched precomps keep protected regions
at their original speed.

New crate effectcraft-model (L2): glTF 2.0 (.gltf/.glb, data URIs, external buffers and
images, PBR metallic-roughness with base/MR/normal/occlusion/emissive textures, node
hierarchy, skins, step/linear/cubic animations) and OBJ/MTL import, parametric primitives,
extruded/bevelled outline meshes and polygon triangulation with holes.
Project: FootageKind::Model, LayerSource::Model/Primitive, Layer::environment, Geometry and
Material Options builders, Environment light Source. Media probes and loads models
(FootageSource::model). Engine: layer.newModel, layer.new3dPrimitive/newPrimitive,
comp.renderer, layer.environment, material.set/reset/duplicateAssign/revealSource (stubs
replaced); File > Import and layer.addItem pick up models. Hand-written fixtures with
attribution sidecars.
