Paper shot export
The "Paper" buttons render at 3× DPR with a white background,
hidden UI, a 2D colorbar, and stage chips. The PDF variant keeps
all overlay text as vector. Enable "iso camera" for a
reproducible isometric angle. Exported figures are rendered in
English regardless of the UI language.
