17 registry blocks that are too big to be one card on the slots page. Each mini-layout below is a live HTML/CSS rendering of that block's shape — the real arrangement of rail, groups, header and content — not a screenshot. It is a shape, not a pixel copy: the real source for each is one click away, taken from the offline registry capture.
Ordered by how close they are to what we already run. Shape rendered live; adoption cost computed from the block's real file count, byte count and registry dependencies.
