"""SKH_P_PTN  (FAMILY=param)
On the SKH01-V1 base, sweep ptn_n in {34,45,55,70,89,110} x atr_win in {10,14,21}.
Slower Donchian breakouts may generalize better OOS. Maximize min-asset HOLD-OUT
subject to minFull>=0.5, fee survives 0.30%RT, >=20 trades BOTH assets, causality ok.
Note standalone DD. Always compare vs V1 (ptn_n=55, atr_win=14).
