MicroSim Layout Reviewer

Purpose

A "MicroSim" is any interactive program embedded in an iframe and built to educational-content standards (docs/sims/<sim-id>/main.html plus metadata, screenshot, index page). The library doesn't matter — p5.js, Mermaid, Chart.js, vis-network, vis-timeline, Leaflet, or hand-rolled HTML/SVG are all valid implementations. What they share is the iframe contract: fixed height, no scroll, embedded inside an MkDocs page.
