/**
 * Draws an epoch millisecond inside the requested bounds.
 *
 * Shared by the `date` and `date-time` generators, which had the same bound
 * expression written twice: `props?.maximum ?? props?.minimum === undefined`
 * parses as `props?.maximum ?? (props?.minimum === undefined)` because `??`
 * binds looser than `===`, so any supplied `maximum` made the condition truthy
 * and was replaced by `Date.now()`, while `maximum: 0` fell through to
 * `undefined + one year` and produced `NaN` (issue #2287). Keeping the
 * resolution in one place is what stops the two copies from drifting again.
 *
 * With no bound at all the window ends at the present instant; with only a
 * lower bound it spans one year from there.
