# Pinned flatc version. The committed bindings (Go + TS) and the
# flatbuffers Go/TS runtimes are all on this version; generating with a
# different flatc silently churns output and can flip nullable-scalar
# wire defaults, so fbs-ts refuses to run on a mismatch. Distro packages
# (e.g. Debian's flatbuffers-compiler) are too old — use the release
# binary at $(FLATC_URL).
