S-corp reasonable-comp / salary optimizer

Finds the S-corporation owner-employee W-2 salary that maximizes after-tax income, trading the payroll tax on wages (6.2% OASDI to the year's wage base + 2.9% Medicare + 0.9% Additional Medicare) against the §199A pass-through deduction's 50%-of-W-2-wages limit and the reasonable-compensation floor. Each candidate salary is priced through the QBI-aware tax engine (threshold phase-in, wage/UBIA limit, SSTB phase-out, the 20%-of- taxable cap, and the OBBBA minimum). Returns the recommended salary and its full breakdown, plus the all-wages baseline and the saving. The only year-keyed datum is the OASDI wage base (grounded to SSA). Deterministic; not tax advice.
