Research direction
Investigate how Coil currently handles animated images on Android (e.g., using ImageDecoder or GIF drawable). Explore iOS image decoding options like ImageIO or CGImageSource for GIF and animated WebP. Review comments on issue #2347 for any proposed approaches. Examine the existing multiplatform module structure to understand where platform specific code should be added.
