  max 512MB), persistent disk cache (OS-appropriate paths), SVG decoder
- DesktopBlurHashFetcher: blurhash placeholder images via Skia Bitmap
- DesktopBase64Fetcher: base64 data: URI image decoding
- SkiaGifDecoder: GIF first-frame rendering via Skia Codec
- MediaAspectRatioCache: thread-safe LruCache for aspect ratios
- NoteCard: inline AsyncImage for image URLs, stripped from text
- Added coil-compose, coil-okhttp, coil-svg, vlcj, commons-imaging,
  androidx-collection deps to desktopApp
