## Omitted optional archive compressor

The upstream `build/ect` Mach-O executable (Efficient Compression Tool, containing multiple bundled libraries) is omitted. It was used only by the legacy js13k ZIP compression step and is not needed to serve or reproduce this native ES module import. The original JavaScript build recipe is retained as provenance; running its optional ZIP optimization step would require supplying ECT separately with its own complete third-party notices.
