Compression codec benchmark

Each matrix compares six codecs across the same five metrics. Cell labels show measured values; background intensity ranks codecs within that dataset.

Reading the matrix: darker cells are better. Memory is inverted because lower usage is preferable. Results remain specific to this run's hardware, software, datasets, and settings.
