Detailed Description

Region B Layer‑1: optimize impinging injector geometry with frozen tanks + throat band.

Targets from Pareto Region B exploration:
  - ``layer1_A_throat_mm2_min/max`` ≈ 2520–2600 mm²
  - Frozen tank stagnation pressures ~644 psi LOX, ~409 psi fuel (mid of 407–411)
  - ``max_fuel_tank_pressure_psi`` / pressure_config fuel cap ≤ 600 psi

Optimizes impinging jet parameters (n_elements, d_jet, spacing, impingement angles) and throat
within the band; L*, D_outer, expansion_ratio pinned from YAML frozen_parameters.

Post-processes ``iteration_history``: re-evaluates diverse near-best candidates and ranks by a
composite of mission error, ΔP/Pc band hinges (LOX [0.15,0.40], fuel [0.40,0.50]), and R hinge
around [0.93, 1.07].

Does **not** modify Cd or injector physics equations.
