# ── Standalone C++ MessagePack Blob library (no SQLite dependency) ─────────────
# A self-contained package — the C++ sibling of the python/, js/, rust/ and go/
# ports. Split into logical translation units (decode, encode, json, mutate,
# iterate) that share private internals via src/msgpack_blob_detail.hpp.
#
# Can be built standalone:
#     cmake -B build cpp && cmake --build build && ctest --test-dir build
# or pulled into the top-level build via add_subdirectory(cpp), which is how the
# repository root reuses the `msgpack_blob_static` target for its C++ ↔ SQLite
# interop tests.
