+# Empty stand-in for `cubecl-cpu`, used via [patch.crates-io] in ../../Cargo.toml.
+# cubecl-cpu is the LLVM/MLIR JIT CPU runtime pulled (transitively, through burn's disabled GPU
+# backends) by harper-core. It drags in the tracel-llvm / tracel-llvm-bundler crates, which build
+# and bundle an LLVM toolchain and are by a wide margin the most expensive thing in the graph.
+# Replacing it with this empty stub removes that whole subtree. Nothing here is ever compiled
+# (GPU backends are off).
