Worked comparison of one 100mm move planned trapezoidally vs jerk-limited, with numerically integrated profiles plotted as small multiples. Figure gains a wide variant and serves SVG unoptimized.

Replaces the thin derivative-control placeholder with a worked comparison:
one 100 mm move planned trapezoidally and jerk-limited, plotted as small
multiples across position, velocity, acceleration and jerk. Profiles are
numerically integrated rather than sketched, and both are constrained to
the same distance and duration so the comparison is fair - which also
surfaces the honest trade, that bounding jerk costs peak acceleration
(882 vs 533 mm/s^2) rather than being free.

Figure gains a wide variant to break dense plots out of the prose column,
and serves SVG unoptimized so the site does not need dangerouslyAllowSVG.
