\caption{Clipping checks using original simulated data and artwork. (a) Geometrically clipped smooth response curves, retaining cubic segments. (b) A dense signal with a narrow peak and an explicit missing-data gap; physical simplification tolerance 0.02 mm. (c) Filled uncertainty-like bands representing supplied simulated intervals, cropped with their outlines. (d) Large boundary markers and thick strokes cropped by a painted window. (e) A synthetic scalar image under a rotated convex window. (f) Glyphs and halos cropped together. (g) Rounded rectangles and an even-odd hole, cropped without changing their source geometry. (h) Nested windows with group opacity beside an unclipped sibling. Letter labels identify checks; the artwork contains no panel titles. Recipe and artwork: MIT, Mark Marosi. No measured data or inferred uncertainty.}
