WFC design session v9: best candidate (Q=64.9, 99.1kHz)

Sweep: Decouple tube wall/cell length around adopted geometry and test multi-cell stacking (1-3) to find Q gains beyond choke-fixed cell tuning

Cell: 22.8mm rod in 29.5mm tube × 76.2mm, 1 cell(s) parallel → C = 1.29nF, water R = 88942Ω. Chokes: 2 × 0.001H (150 turns, AWG 20, 18m wire, AC R 0.9Ω each). At resonance f_r = 99.08kHz: Xl = 1245Ω, Xc = 1245Ω, tank Q = 64.9, coil Q = 707.5. Cell voltage 779V from 12V drive (×64.9), series current 625.4mA. All constraints satisfied (current <1A, band, wire length). Score 0.717.
