Designs an L-network impedance matching circuit between two real impedances at a given frequency. Computes the required shunt and series reactive components (inductor and capacitor) to transform the source impedance to the load impedance. The network Q factor is sqrt(Rh/Rl - 1) where Rh is the higher impedance. Topology is automatically selected: the shunt element is placed across the higher impedance side. Essential for antenna matching, amplifier input/output matching, and maximizing power transfer. Chain from lc_resonance to match at a tank circuit's resonant frequency.
