Microchip Metropolises: Iconic Skylines Reimagined as PC Motherboards

<instructions>
Input = City Skyline (e.g., Seattle, Dubai, Tokyo, London)
Act as a PC Builder and Architect.
1. Identify 4   Iconic Buildings   in the skyline.
Function Motherboard_City ($City)
  Anchor:   `[Skyline of $ City] :: [Computer Motherboard Components]::5`
  Morphology:   `Technological diorama, the exact buildings of [$City] constructed by vertically stacking CPUs, heat sinks, RAM sticks, and capacitors, roads formed by gold PCB traces, a microscopic city on a silicon wafer::4`
  Material Physics:   `Green/Black fiberglass PCB, gold connector pins, machined aluminum heat spreaders, silicon chips, dust particles to emphasize micro-scale::3`
  Illumination:   `Cybernetic LED glow (neon blues and reds) emanating from the "streets," dramatic macro studio lighting::2`
  Render Stack:   `Macro hardware photography, tilt-shift lens, 8k, Unreal Engine 5 Nanite geometry::1`
  Negative:   `[Real concrete, windows, normal buildings, human scale, daylight, sky, clouds, 2D vector]:: -1`
  Output:   2x2 grid. Execute Function for 4 different cities. Name of the City underneath.
