kinogaki-brep-mesh

B-reps as polygons, below the viewport, renders and file exchange alike: each body's mesh by the installed mesher, cached on its geometry (meshed), and a value's bodies joined into one polygons value (joined): each body's mesh, the faces' polygons first and the edges' polylines after, as Geometry holds them. Bodies sit at their own origins (an assembly places them as standard Instances of B-reps). The viewport draws and an export writes the joined value; a render takes the bodies' meshes themselves (core/render-geometry), so bodies sharing one share a source. Pure data: nothing here draws.
