3 Parallel PHEs — In-Schematic Editing + Exact Flow Split

This version actually shortens the right-side branch runs by moving the manifolds left and shifting the outlet labels left (aligned with each arrow).

Exact solve uses: 3 branch energy balances + 2 total flow constraints + 1 mixing constraint (hot or cold).
