+* Go back to the upstream pi release tarball once Bun's --compile bug is
+  fixed.  Bun 1.2.20-1.3.11 produces broken binaries; 1.3.14 fails entirely on
+  this system (kernel 7.0.12, glibc 2.39).  When a fixed Bun is available, just
+  download the tarball, extract the binary, and wrap it - no build step needed.
+  Remove the npm-install-build-system wrapper and the Node.js dependency in
+  conf/home/pi.scm.
