     * Node runs this code directly — `node server.ts`, type-stripping, no bundler — so it
     * is Node's ESM resolver that decides whether an import resolves, and that resolver
     * does NOT guess extensions: `./liveAudioConfig` is a missing module, only
     * `./liveAudioConfig.ts` is a file. `moduleResolution: nodenext` is what makes tsc
     * apply that same rule, so `npm run typecheck` fails on an extensionless relative
     * import instead of the server failing to boot at runtime.
     *
     * This matters most for the modules under src/ that both halves share
     * (liveAudioConfig, transcriptKeys, slideTranslation...): tsconfig.app.json checks
     * them under `bundler` resolution, where extensionless is legal and Vite resolves it
     * happily — vitest included. Nothing in the browser-side toolchain can notice the
     * break, so the server's own project has to.
