/**
 * Prints candidate regression floors for review; never updates the gate automatically.
 * Run: pnpm exec tsx src/a11y/contrast/printRegressionFloors.ts
 *
 * Compare the output with contrastPairs.ts. Raising a floor locks in an improvement;
 * lowering one permits a regression and requires an explained, intentional token change.
 * A null measurement requires investigation, not an automatic new skip.
