Transmit High-Density Text Blocks Efficiently using Base85

Base85 (also called Ascii85) is an extremely compact binary-to-text encoding scheme. By utilizing a larger character set than standard Base64 (85 characters vs 64), it reduces payload size overhead from 33% down to only 25%, making it ideal for packaging PDF documents, git patches, and system configs.
