The reference implementation. Asset panel, GPU-accelerated preview, timeline, audio, transitions, and MP4 export — all wired together.

Isolated timeline interaction model. The full editing surface without the renderer — useful for testing integration or building a custom rendering layer.

Step through the export worker frame-by-frame. Visualizes the resolveTimeline → OffscreenCanvas → VideoEncoder pipeline.

GpuDebugCounters visualizer — draw call counts, texture uploads, frame timing, and context-loss simulation.
