# In a checkout, zena-cli reads its CLI module (packages/zena-cli/out/zena.wasm) and the standard library
# from the tree, so the build has to produce both, not just the binary.
# Zena's package.json asks for Node 25, but Tangled's Nixery stops at 24, and on 24 this commit builds
# engines byte-identical to a Node 26 build, so the engines check is turned off.
