 * BaseButtonOverlayHtml Component
 * 
 * HTML button with Korean theming (no Three.js dependency).

 *
 * Optimized with React.memo for 60fps performance:
 * - Prevents re-renders when props haven't changed
 * - Event handlers already use useCallback internally
 * 
 * @example
 * ```tsx
 * <BaseButtonOverlayHtml
 *   korean="확인"
 *   english="Confirm"
 *   onClick={() => handleConfirm()}
 *   variant="primary"
 *   size="md"
 * />
