SplatHash: Image Compression to 16 Bytes with 32×32 Preview Reconstruction

Master baker tier. Every paragraph earns its place on the tray.
Summary
SplatHash is a new image compression algorithm that encodes any image into exactly 16 bytes (22-character base64url string) and can reconstruct a 32×32 blurry preview in just 0.067 milliseconds. It's similar to existing solutions like BlurHash and ThumbHash but offers smaller size. The project provides implementations in Go (reference), TypeScript/JavaScript, and Python, all producing bit-for-bit identical hashes. The article serves as technical documentation and installation guide for developers.

Go is the reference implementation. All others are verified bit-for-bit against it.
