Grid-painted surface estimator
A fourteen by nine grid where the area to cover is painted by dragging with mouse or finger, computing real surface, a true perimeter that counts only cell edges without a painted neighbour, the pieces needed including waste, and the cost. A connected-components sweep detects when the selection breaks into several pieces, colours each one apart and warns about it, while the figures ease between values during the drag.

How this catalog works
Every component ships with its reproduction prompt: the text you paste into an AI builder to get exactly this piece. The values above are editable, and the prompt you copy carries the ones you chose, so what gets generated is what you were looking at.
