Dictionary Compression

Dictionary compression is an advanced compression technique where a shared "dictionary" of common data patterns is used to compress multiple files more efficiently than compressing each one individually. Speed Kit uses this for HTML documents, which can reduce their size by 80-90% beyond standard compression. This makes features like Predictive Preloads extremely bandwidth-efficient.
