Feasibility inspection only — no coaching or verified 3D anatomy.

Yellow: selected rider crop. Cyan: raw Vision joints (2D points below 0.2 confidence hidden). Numbers: fixed joint IDs shared across every image and both pose types. Each PNG includes its own legend beside the photo; expand the table for source coordinates. Left/right always means the rider’s anatomy. Pink circles: provisional source-only references and their uncertainty. Source pixels are preserved beneath annotations.

Source-photo identity and multi-rider crop review by Codex, 2026-09-15, before detector run. Folder name retained as supplied grouping, not verified capture date. No ground-truth landmarks.
