Detailed Description

Exploration run: relaxed fuel ΔP band + reduced fuel tank pressure *upper* bound via pressure_config.

Layer-1 uses (see layer1_static_optimization):

    P_F bounds = [max_fuel_pressure_psi * 0.65, max_fuel_pressure_psi * 0.85]

Setting pressure_config[\"max_fuel_pressure_psi\"] = 900 gives ~585–765 psi search band.

Also overrides requirements for this session:

    injector_dp_ratio_F_max = 1.50  (oxidizer band unchanged from YAML)
    W_MOM = 300
    W_geom_ao_af_momentum = 2800

Then: AO/AF evaluate sweep [1.8, 2.5] at optimized tank pressures,
      Cd sensitivity grid (0.9/1/1.1)× on Cd_inf and Cd_min per propellant (in-memory copies only).

Does not modify YAML or committed Cd defaults.
