Error building in dev container: falling back to java version of closure compiler / google-closure-compiler returned non-zero exit status 254

Start with Makefile:94 and the emcc invocation shown in the npm run rebuild log; reproduce the closure compiler failure in the ARM64 dev container and inspect how that compiler is selected. Done means npm run rebuild completes and produces dist/sql-asm.js without the non-zero exit status.

I'm on an ARM64 Mac Book Pro, running the DevContainer in VS Code.

After a fresh checkout, no pending changes, npm install and then npm run rebuild, I get this error:
