 * Calculates ROI estimate based on security levels

 * @example
 * ```typescript

 * const roi = calculateROIEstimate('High', 'High', 'Moderate');
 * console.log(`ROI: ${roi.value}, ${roi.description}`);
 * // Output: ROI: 150-250%, Significant risk reduction
 *
 * // Calculate ROI for moderate security
 * const moderateROI = calculateROIEstimate('Moderate', 'Moderate', 'Low');
 * console.log(moderateROI.value); // "100-150%"
