/*
 * Breadboard Power Supply Comparison - sourced comparison table
 *
 * Built on the comparison-table template conventions (aliceblue control area,
 * white table surface, 5-step star colour scale, pill badges) with two
 * additions this sim needs:
 *   - every specification cell is a <button>, because clicking it opens the
 *     citation behind that number
 *   - a verdict dot on each cell, colour-coded by how solid the number is
 *
 * Target: <iframe src="main.html" height="842px" width="100%" scrolling="no">
