```python
def fleet_hops(count: int, lts: list, builds: list, hop: int) -> int:
    """
    Calculate the total number of hops required to bring every device in the fleet
    to the newest release.

    A device starts at release i. A hop can reach at most release i + hop.
    However, a hop may never pass a long-term-support (LTS) release without
    landing on it. Therefore, the device lands on the lowest LTS release strictly
    above i and strictly below the release it would otherwise reach. If the
    device would otherwise reach a release that is not an LTS release, it lands
    on that release. If the device would otherwise reach beyond the newest release,
    it lands on the newest release.

    The function returns the total number of hops across all devices, counting
    each device separately. A device already on the newest release requires no
    hops.

    Parameters
    ----------
    count : int
        The total number of releases, numbered from 0 (oldest) to count-1 (newest).
    lts : list
        A list of LTS release numbers. The list may be in any order.
    builds : list
        A list of release numbers for each device in the fleet.
    hop : int
        The maximum number of releases a single hop can cover.

    Returns
    -------
    int
        The total number of hops required to bring every device to the newest release.

    Raises
    ------
    ValueError
        If any release in `builds` is not a whole number in the range [0, count-1].
