+# Standalone bootstrap for the sandbox IPC tests — JUCE only, no cmake-js /
+# node-addon-api / ONNX. Lets a Linux-only developer (and the lightweight
+# `sandbox.yml` CI job) build + run the loopback / control / spawn tests
+# without configuring the whole native addon.
+#
+# Usage (from the repo root):
+#   cmake -S tests/sandbox/standalone -B build/sandbox -DCMAKE_BUILD_TYPE=Debug
+#   cmake --build build/sandbox
+#   ctest --test-dir build/sandbox --output-on-failure
+#
+# Sanitized variants:
+#   cmake -S tests/sandbox/standalone -B build/sandbox-tsan -DSLOPSMITH_SANITIZE=thread
