WFC design session v18: best candidate (Q=97.8, 95.9kHz)

Sweep: hold surface_factor at 0.25; push ppm below the 0.1 knee and temperature toward 0°C to test if current drops below 900mA

Cell: 15.9mm rod in 20.7mm tube × 76.2mm, 1 cell(s) parallel → C_eff = 1.39nF, bulk water R = 128442Ω. Water/electrodes (Randles): 0.1ppm Na+ @ 3°C, surface ×0.25 → λ_D 227nm, C_dl 1.8µF, cell series R 11.1Ω, displacement current 99.1%, breakdown margin ×137. Chokes: 2 × 0.00099H (129 turns, AWG 18, 15m wire, AC R 0.6Ω each). At resonance f_r = 95.91kHz: Xl = 1193Ω, Xc = 1193Ω, tank Q = 97.8, coil Q = 1068.2. Cell voltage 1173V from 12V drive (×97.8), series current 983.5mA. All constraints satisfied (current <1A, band, wire length). Score 0.832.
