Mathematical curve for smooth, human-like mouse trajectories. Straight-line movements are a bot fingerprint.

A Bezier curve defines a smooth path between two points using control points that pull the line into natural arcs. In browser automation, replacing straight-line moveTo(x, y) with Bezier interpolation produces mouse trajectories that curve and accelerate like a human hand. Cubic Bezier (4 control points) is the standard for anti-detection because it captures the slight overshoot and correction that real mouse movements exhibit.
