# standalone-hoist-pnpm.sh — Hoist pnpm .pnpm packages to top-level node_modules
#
# The Next.js standalone build with pnpm stores traced dependencies inside
# .pnpm/<package>@<version>/node_modules/. Node's require() can't resolve
# bare imports like require('next') from that structure because the top-level
# symlinks that pnpm normally creates don't survive npm tarball packing.
#
# This script copies each package from .pnpm/*/node_modules/ to the
# standalone root node_modules/ so require() works in global npm installs,
# then removes .pnpm to avoid file duplication in the tarball.
