/**
 * ============================================================================
 * Media Type Options Schema
 * ============================================================================
 *
 * The `options` field provides type-specific configuration for media types
 * (image, video, audio). Below are the recommended schemas for each type.
 *
 * ============================================================================
 * IMAGE Type Options
 * ============================================================================
 *
 * Example:
 * {
 *   type: 'image',
 *   options: {
 *     // File formats
 *     accept: ['jpeg', 'png', 'webp', 'gif'],  // Allowed formats
 *
 *     // Size constraints
 *     maxSize: 10485760,      // Max file size in bytes (10MB)
 *     maxWidth: 4096,         // Max width in pixels
 *     maxHeight: 4096,        // Max height in pixels
 *     minWidth: 224,          // Min width in pixels
 *     minHeight: 224,         // Min height in pixels
 *
 *     // Multiple uploads
 *     multiple: true,         // Allow multiple images
 *     maxFiles: 10,           // Max number of files
 *
 *     // Thumbnail generation
 *     thumbnail: {
 *       enabled: true,
 *       width: 200,
 *       height: 200,
 *       format: 'jpeg',       // 'jpeg' | 'png' | 'webp'
 *       quality: 85           // 1-100
 *     },
 *
 *     // Preview settings
 *     preview: {
 *       enabled: true,
 *       maxWidth: 1024,
 *       maxHeight: 1024
 *     },
 *
 *     // Metadata extraction
 *     metadata: {
 *       extractExif: true,           // Extract EXIF data

 *       extractColorProfile: true    // Extract color profile
 *     },
 *

 * ============================================================================
 * Label Studio Integration
 * ============================================================================
 *
 * Dataset media types map to Label Studio annotation types:
 *
 * - image → <Image name="image" value="$image"/>
 * - video → <Video name="video" value="$video"/>
 * - audio → <Audio name="audio" value="$audio"/>
 *
 * Example Label Studio config generation:
 *
 * const dataItem = { name: 'product_image', type: 'image' }
 *
 * // → Label Studio config
 * <View>
 *   <Image name="product_image" value="$product_image"/>
 *   <Choices name="classification" toName="product_image">
 *     <Choice value="Good"/>
 *     <Choice value="Defect"/>
 *   </Choices>
 * </View>
