/* Layout: a chip seen from the top down. Graphite "die" bands alternate with wafer-silver bands; mask-layer
   colours (metal 1, metal 2, poly, diffusion, metal 3) appear only where the content is about layers.
   Copper is the single action colour. One deliberate look, so colours are set explicitly for every host theme. */
