 * Human-like input timing.

 * Robotic automation moves the mouse in straight teleports and types at a
 * perfectly fixed cadence. Behavioural-fingerprinting scripts (Akamai, PerimeterX,
 * Datadome) watch for exactly that. We move along a curved path with eased,
 * jittered timing and vary keystroke intervals around human norms.
 *
 * Determinism note: we draw randomness from a seedable PRNG so runs can be made
 * reproducible for tests, while still being non-uniform on the wire.
