/*
 * PowerShell vs. WSL Comparison Infographic
 * Designed for iframe embedding with minimal padding/margins.
 * Target: <iframe src="main.html" height="820px" width="100%" scrolling="no"></iframe>
 *
 * Lessons learned:
 * - Pure-CSS attr() tooltips can't hold multi-line <pre><code> content, so
 *   this sim uses a single floating #infobox positioned in JS instead.
 * - Hover shows the infobox; a click/tap pins it open (touch devices have
 *   no hover), and clicking the (i) again, the close button, outside the
 *   box, or Escape all dismiss it.
