# The gateway only ever compresses outbound frames at level 3 (ZSTD dfast) and
# levels 1-2 (ZSTD fast). Exclude every higher match-finder from the zstd-sys C
# build so the streaming compressor does not pull libzstd's large optimal-parse
# code into the wasm bundle. These defines are read by the cc crate when it
# compiles zstd-sys for the wasm target. Decompression is unaffected.
