Fittings ΣK
Couples the receiver-pressure track with the downstream pipe ΔP: point-of-use pressure = tank pressure − network ΔP (solved iteratively). Set pipe ID or length to 0 to disable.
A row with bore ≤ 0 or duty outside 0–100 % is skipped. Offset staggers the actuator's cycle within the shared cycle time.
Set compressor flow to 0 to size the receiver against the cycle-average demand.

Batch / CSV import (condition table)
One branch per line (B1–B4): demand flow, Δp budget, bore and length. 0 = no demand / shared budget; branches not listed are cleared.
Default column order: demand flow · Δp budget · bore · length. Add a header line (q dp d l) to reorder, or drop a CSV file.
Export writes the same condition table back out, so the saved file can be loaded again.
