Interpolation inspector
Sweep the weight axis and watch the three-master interpolation. Master positions are exact; the midpoints between them are where shape drift appears first.

Glide interpolates its whole 100–950 axis from three masters — Thin (100), Regular (400) and Extra Black (950). The amber columns (250, 675) are pure interpolations sitting farthest from any master, so shape drift shows up there first. Compare a flagged glyph like $ or S against a clean one like o across the ramp.
