/* NeuralMill — GLASS SYSTEM.
   Derived from the product concept renders: translucent frosted panels floating in 3D over a
   near-black stage, lit from the top edge, with a cyan edge-glow frame and warm amber circuit
   traces behind. This is the "instrument in space" layer that sits on top of the flat lab-site UI. */
