Struct HumanoidRenderState 

pub struct HumanoidRenderState<'a> {
    pub main_hand: Option<&'a ItemStack>,
    pub off_hand: Option<&'a ItemStack>,
    pub main_arm_left: bool,
    pub use_hand: Option<Hand>,
    pub ticks_using_item: i32,

    pub off_arm_pose: ArmPose,
}

Borrowed humanoid inputs at arm-pose extraction, shared by players and mobs. Poses are in main/off-hand order, before listeners answer; item declarations are already included. Model-specific animation may subsequently adjust the arms.
