-# Fix voor OOM Killer: dwing de Node-compiler om agressief op te ruimen bij 4GB RAM
+# The build runs the webpack builder (see the `build` script in package.json).
+# Turbopack's compiler is a single native process that grows past 12GB RSS on
+# this 329-route app and gets OOM-killed; webpack peaks around 5GB. A
+# --max-old-space-size cap does NOT help, because that memory is native
+# Turbopack memory rather than the V8 heap.
