/* Wi-Fi Heatmap Planner — an editor first, a page second.
 *
 * The plan is the product, so it gets the width: the canvas takes what the
 * page has and the inspector sits beside it on a desktop and under it on a
 * phone. The site preset (`terminal`) supplies type and surface; the heatmap
 * and wall colours are fixed, because they encode data and must read the
 * same on every theme and on paper.
