HAZOP deviation evaluator (standalone)

A single-deviation calculator that runs IEC 61882 HAZOP logic, CCPS LOPA risk math, and IEC 61511 SIL-gap logic on one form and produces an FM-EN-17 PHA datasheet — a quick alternative to opening the full multi-node workspace for a one-off deviation.

• You need to check or document a single deviation and don't need a full multi-node study.
• A quick sanity check on whether a scenario's LOPA math implies a SIL gap before committing to a full study.

Runs the identical HAZOP/LOPA/SIL-gap logic as the full workspace against a single deviation, then renders it straight to a printable FM-EN-17 datasheet.
