/**
 * Media Variants Repository
 *
 * Data access layer for media_variants table.
 * Provides normalized storage for file variants (thumbnail, mobile, desktop, 4k).
 *
 * Use this repository when you need to:
 * - Query variants by name (e.g., "find all thumbnails")
 * - Query variants by dimensions
 * - Aggregate variant storage usage
 * - Clean up orphaned variants
 *
 * For simple variant access, use FilesDatabaseRow.variants JSONB column instead.

 * Media Variants Repository
 *
 * Extends BaseRepository for normalized variant storage and querying.
 *
 * Inherited from BaseRepository (used directly):
 * - findById(id) - Get variant by ID
 * - delete(id) - Delete variant
 * - exists(id) - Check if variant exists
 * - query() - Fluent QueryBuilder
 * - count(filter) - Count variants
 * - findOne(filter) - Find single variant
 *
 * Domain-specific methods:
 * - findByMediaId(mediaId) - Get all variants for a media file
 * - findByVariantName(name) - Get all variants of a specific type
 * - findByMediaIdAndName(mediaId, name) - Get specific variant for a media file
 * - deleteByMediaId(mediaId) - Delete all variants for a media file
 * - getTotalSizeByMediaId(mediaId) - Get total storage size for a file's variants
