+   qft-variations-positions.mjs — sketch 03.
+   Hold the palette CONSTANT (per-field monochrome — each field
+   one clear hue so the eye can track its position) and vary
+   only origin / scale per field. Some fields deliberately
+   extend past the canvas edge (scale > 1).
+   Output → output/qft/sketch03/
