This 2D companion turns the 3D "Circuit Board City" skyline into an actual power-delivery-network analysis: a supply drives a trunk trace to a junction that fans out into seven parallel component loads, and every trace's resistance is derived from real copper geometry (width, copper weight, length, temperature) rather than decoration. Adjusting supply voltage, trace width, copper weight, board temperature or load intensity re-solves Kirchhoff's current and voltage laws across the network live, recoloring every trace by its instantaneous power dissipation (P=I²R) and flagging any trace whose current density exceeds a safe external-layer rating.
