Every pane you see was placed by an algorithm that has no idea what a cathedral is. It scatters sites on concentric rings around a hidden centre, then cuts each site's territory with the perpendicular bisector of every other site — a Voronoi tessellation, computed the long way, one half-plane at a time. What survives is a rosette: five colour sectors braided across five rings, so no two neighbours share a hue.
The lead is not a stroke drawn on top. It is the gap between territories, thickened until the glass has a skeleton. Quench a pane and you remove its light but not its outline: the window remembers where the piece used to be.
