/**
 * Stazora Brokers Visual: hub with lines (inc/brokers-visual.php loads it on the article only).
 * Dimensions follow the Magic UI AnimatedBeam demo: 300 px stage, 40 px padding, 512 px wide grid, 40 px row gap,
 * 48 px nodes with 2 px border, 64 px centre. Node labels are absolute so they never change that geometry.
