• An actor's health as a whole percentage of its maximum.

    Returns undefined — rather than 0 — whenever there is no usable health to report (absent, or a non-positive maximum), so "nothing to show" stays distinct from "at death's door". Shared by every roster that lists other actors' condition (a cohort's members, a vehicle's occupants).

    Parameters

    • health: undefined | { max: number; value: number }

      The actor's token-bar-shaped health, if any.

    Returns number | undefined

    The percentage 0…100, or undefined.
