+Each Python worker starts the TypeScript bridge with `vite-node --mode
+balance-lab`. That dedicated mode disables Vite's public directory and ignores
+all filesystem-watch paths because a headless, one-shot simulation does not
+need hot reload. Keep this isolation in place when changing `vite.config.ts`:
+parallel workers must not consume one watcher per shipped asset. If an older
+deployment exhausts the host watcher limit, the job now reports that specific
+startup failure instead of only the subprocess exit code; deploy the no-watch
+runtime fix rather than increasing the host's watcher allowance.
