    ///
    /// This archetype provides configuration for how state values are displayed.
    /// It maps raw state values to display labels, colors, and visibility.
    ///
    /// `values`, `labels`, `colors`, and `visible` are parallel arrays: the entry
    /// at index `i` of each describes the same state value, and only the
    /// per-index pairing is meaningful. The four arrays should have matching
    /// length; any secondary array (`labels`, `colors`, `visible`) that is shorter
    /// than `values` falls back to defaults for the missing entries.
    ///
    /// It's generally recommended to log this type as static.
    ///
    /// The underlying data needs to be logged to the same entity path using `archetypes::StateChange`.
    ///

    ///         rerun::RecordingStream("rerun_example_state_configuration");
    ///     rec.spawn().exit_on_failure();
    ///
    ///     // Configure how each raw state value is displayed (label, color, visibility).
    ///     rec.log_static(
    ///         "door",
    ///         rerun::StateConfiguration()
    ///             .with_values({"open", "closed"})
    ///             .with_labels({"Open", "Closed"})
    ///             .with_colors({0x4CAF50FF, 0xEF5350FF})
    ///     );
    ///
    ///     rec.set_time_sequence("step", 0);
    ///     rec.log("door", rerun::StateChange().with_state("open"));
