+ * // Returns: { type: 'natural', order: 'asc', ignoreCase: true }

+ * ```ts
+ * // Invalid setting throws error:
+ * getSettings({
+ *   perfectionist: {
+ *     type: 'natural',
+ *     invalidOption: true, // This will throw
+ *   },
+ * })
+ * // Throws: Error: Invalid Perfectionist setting(s): invalidOption

+ *
+ * @param settings - ESLint shared configuration settings object.
+ * @returns Validated Perfectionist settings or empty object if none configured.
+ * @throws {Error} If invalid settings are provided.
