Detailed Description

Region B Layer‑1: impinging geometry + **co-optimized** tank pressures (narrow bands).

- ``layer1_A_throat_mm2_min/max`` = 2520–2600 mm²
- LOX tank search: ``layer1_P_O_start_psi_min/max`` default 580–700 psi
- Fuel tank search: ``layer1_P_F_start_psi_min/max`` default 350–500 psi
- ``pressure_config`` caps: max LOX 700 psi, max fuel 500 psi (for ratio guidance in Layer‑1)
- ``layer1_infeasibility_gate_eps`` = 2e-3 (see ``layer1_static_optimization``)

Post-process: re-evaluates history + best point; ranks by lexicographic priorities:

  1. Thrust near 8000 N  
  2. MR near 3.5  
  3. R near 1  
  4. Fuel ΔP/Pc near [0.40, 0.50]  
  5. Minimize LOX ΔP/Pc (lower is better)  

Does **not** change Cd or injector physics.

Example::

  python scripts/run_layer1_region_b_coop_pressures.py \\
    --output-csv output/layer1_region_b_coop_ranked.csv
