- PNG failed because wasm-bindgen's init only accepts a URL string (or a
module/buffer): passing { module_or_path } broke every PNG optimization.
- GIF/APNG showed flashing colors because patches were written with
putImageData, which ignores the transparency that means "keep the
previous frame". Patches now blend through drawImage with correct
disposal handling, and quantization keeps a transparent palette entry.
- Video no longer downloads the whole file into memory: Mediabunny reads
it with range requests (UrlSource) and the muxer streams into Blob
chunks (StreamTarget) that are assembled with last-write-wins range
merging. BufferTarget held the entire output in memory, which crashed
the tab on large files.
