Conventions

Videos come in a fixed order; the next one starts automatically when one is done. Frames load from the server — no video files needed (a video without hosted frames asks for its local file).
One still frame at a time, three questions per frame — all judged against the lead shoulder.
1/2/3 answers the highlighted question; the third answer saves & advances.
Revisiting a labeled frame shows its answers in green — click a different option to change it; that one click re-saves & moves on.
Hover the frame for a guide cross — the horizontal line checks height, the vertical line checks front-to-back.
Esc = restart this frame's answers.
Ctrl/Cmd+scroll (or pinch) = zoom · drag = pan · double-click = reset zoom.
While zoomed, each new sample re-centers on the chin.
←/→ = peek at neighboring frames.
R = back to the sampled frame.
U = clear this sample's saved label.
S then 1/2 = skip (occluded / unclear).
Esc = cancel the skip menu.

Judge the chin against the LEAD shoulder at the shown frame. Answers run good → bad. Height: is the chin under, level with, or over the shoulder? Front to back: is the chin behind, same as, or in front of the shoulder? Kissing: is the chin close enough to (almost) kiss the shoulder?
