# A genuinely static, single-file nepali-core-cli - real portability
# proof, not just "no libpython dependency" (see the feature-gating
# commit). rust:alpine is musl libc natively, so a normal `cargo build`
# here produces a fully statically-linked binary with zero runtime
# library dependencies at all - verified with `file`/`ldd` in the build
# log, not assumed. Built with rust-interop + js-interop only
# (python-interop needs a real libpython, which is fundamentally
# incompatible with a single static binary until pyo3 supports static
# embedding - see CLAUDE.md).
