Tracker panel (Window > Tracker): Track Camera / Warp Stabilizer (disabled),
Track Motion / Stabilize Motion, Motion Source, Current Track, Track Type,
Position/Rotation/Scale, Motion Target with Edit Target..., Options...
(Motion Tracker Options dialog), Analyze (1 frame back, back, forward,
1 frame forward; stop while running) with progress, Reset and Apply (Apply
Dimensions dialog). Track point widgets in the viewer: feature and search
regions with corner handles, attach point crosshair and track path, all
draggable through track.setPoint (one undo step per drag). Automation ids for
every widget; headless UI test.
Tracker: featureless regions no longer drift (ties keep the prediction, only
confident matches predict motion). docs/agents.md: tracking example.

New L2 crate effectcraft-track: per-point feature/search region tracking with
pyramid normalized cross-correlation and Lucas-Kanade (similarity + gain/bias)
sub-pixel refinement, confidence, adapt/stop/extrapolate/continue actions,
RGB/luminance/saturation channels, blur/enhance pre-processing, and
homography/affine/similarity solves.
Project: Motion Trackers > Tracker n > Track Point n property tree
(GroupKind::Tracker with type, target and options). Engine: track.* commands
(new/motion/stabilize/property/select/setType/setTarget/options/setPoint/
analyze/stop/apply/reset/delete/status), background or blocking analysis
job with progress and cancel (one undo step), apply to Transform, Stabilize
and Corner Pin. Renderer::layer_source for the tracker's frames.
