/*
 * Spawn Zone - Looming Stimulus Control Script
 * 
 * Manages when and where looming stimuli appear during experiments.
 * Implements habituation period (minimum safe crossings) before threat
 * introduction, with probabilistic spawning.
 * 
 * Experimental Design:
 * - Allows initial safe trials for habituation
 * - Probabilistic spawning prevents predictability
 * - Single stimulus at a time (prevents overwhelming)
 * - Resets spawn eligibility on zone exit
