// src/components/lifetime.rs

/// Runtime-only countdown on an entity: seconds remaining before it is
/// automatically removed. A spawn carries it onto short-lived instances
/// (projectiles, debris, timed effects); the graphics step decrements it each
/// frame and despawns the entity (and its descendants) when it reaches zero,
/// reclaiming the GPU draw slots for reuse. World authors never declare this
/// type directly; it is set at spawn time.

    /// Seconds left before the entity is despawned.
