Interface anatomy
Three annotated regions of the actual released interface. Selecting a layer outlines its region without hiding the others. This is a fixed screenshot, not live DOM inspection.

Content: The host supplies the title, caption, node names and four scripted steps. The visible explanation describes illustrative matches, not a real search response.

Structure
The released component lays out an ordered lane of three nodes and directional edges. This is HTML and CSS, not the SVG graph proposed in the early plan. The screenshot fixes one desktop layout; the live player also adapts to narrow containers.

Interaction
Playback buttons and a selectable step list belong to the package. The portfolio supplies data and labels; it does not drive playback. Visible state labels complement color. Manual screen-reader verification is still open.

The captures show the interface in English and in a light theme.
