/**
 * Two 0805 inductors, L2 rotated 90°, placed so their courtyards overlap.
 *
 * 0805 courtyard: width=3.35mm, height=1.9mm.
 * L1 (0°) at (0,0): courtyard x=[-1.675, 1.675], y=[-0.95, 0.95].
 * L2 (90°) at (2.5, 0): with pcb_courtyard_outline the polygon rotates correctly,
 *   so effective x=[-0.95,0.95], y=[-1.675,1.675] shifted → x=[1.55, 3.45].
 * Courtyards overlap in x at [1.55, 1.675].
 * Pads of L2 are at x=2.5±0.5125, well clear of L1's pads ending at x=1.425.
