Generated a real 3-tier architecture diagram: the skill's mxCell conventions (html=1, fillColor tiers, cylinder DB shape, legend) produce XML that actually renders correctly in draw.io, while a naive from-memory attempt used bare style strings (no html=1, no fill, no arrowheads) that draw.io renders as broken unstyled boxes.
