GIFs went through the still-image path, so an animated GIF came in as a
single frame with zero duration. A GIF with two or more frames is now
probed as a movie: its frame rate is chosen so every per-frame delay is
a whole number of frames (uneven timing is kept exactly), delays of 0
or 1 hundredths count as 10 like in browsers, and the pool decodes the
frame shown at the requested time. A single-frame GIF stays a still.

Image sequences were found only by the desktop media prober: one picked
numbered still brought its whole run, with no way to import just that
frame, picking every frame made one sequence item per frame, the browser
couldn't make sequences at all, and a gap in the numbering closed up
silently.
The engine now groups numbered stills itself (engine/src/sequence.rs):
one picked file brings its run from its folder, several picked files of
one run import as that range, a picked or dropped folder imports its
files with each run as a sequence, and Force Alphabetical Order takes
every image of that type in the folder by name. `file.import` takes
`sequence` (default on), `alphabetical` and `frameRate`; Replace Footage,
Reload, proxies and render outputs probe the same way. The media layer
probes one file; the browser lists its file table for the run and
registers every frame with its media pool.
File > Import > File... asks, like After Effects' "PNG Sequence"
checkbox, whether picked numbered stills import as a sequence, with
Force Alphabetical Order and the frame rate. Sequences are named
`shot_[0001-0250].png`.
Interpret Footage gains Missing Frames (Show Placeholder, colour bars as
in After Effects, the new default; Hold Previous Frame; Skip) and Start
Frame (the frame number at the footage's first frame: trims or pads the
head). Saved projects keep Skip, so their sequences play as before.
Form notes keep a readable width and the form fits its rows, so OK stays
in view. docs/footage.md explains importing footage and sequences.
Test: tests_sequence (engine: run, picked range, every frame, Sequence
off, folder, alphabetical, Interpret Footage Missing Frames / Start
Frame, Replace Footage and Reload), project sequence unit tests,
sequence_gaps_show_placeholders_hold_or_close_up (media),
import_dialog_offers_the_image_sequence_option and
dropped_frames_import_as_one_sequence_with_sequence_interpretation (UI).

The smart-object branch of the layered-file decoder bound the footage layer twice and
re-read it with expect("embedded implies a layer"); bind it once with a let-chain. Denies the
panic lints in the crate.

Aux-channel model (effectcraft_raster::channels3d: depth, object/material
ID, normals, UV, coverage, Cryptomatte ranks + manifests, MurmurHash3);
EffectHost::aux; multi-layer OpenEXR channels via the exr crate
(FootageSource::aux); the compositor's depth / layer-ID / Cryptomatte pass
(Renderer::comp_aux) so the effects work on precomps of 3D comps.

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

(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.
