/**
 * Direct matrix-level tests for gates.ts.
 *
 * Every test here operates on the raw Gate2x2 / Gate4x4 numbers — no Circuit,
 * no simulation backend, no measurement sampling.  This separates gate-matrix
 * correctness from circuit-engine correctness.
 *
 * Things NOT tested here (covered by circuit.test.ts via Circuit.run()):
 *   behavioural outcomes, measurement distributions, Ramsey fringes, Bell-state
 *   production, controlled-gate firing, algorithm-level identities.
