manual-is-finite

Prefer .isFinite() over equivalent infinity comparisons

Strict infinity bounds and an absolute-value comparison with positive infinity perform the same finite-value classification.
Instead, you SHOULD call .isFinite() on that value.

Paired != checks are excluded because NaN satisfies both comparisons.
