Implement the canonical Battery indicator component (hardware.battery). Battery indicator: A software representation of a physical device, state, or tactile control. Support these states: default, hover, focus-visible, active, disabled. Use semantic design tokens rather than raw visual values. Preserve a minimum 44px touch target where interactive. Provide and verify: implementation, state-matrix, responsive, keyboard, touch, reduced-motion. Keep the component API stable so every Studio kit can supply its own rendering without changing the behavior contract.Studio contract
