# The bind mount (.:/app) provides workspace-level node_modules symlinks from
# the *host*, but those symlinks target the root node_modules/.pnpm store.
# Inside the container, /app/node_modules is a named volume whose pnpm
# content-addressable hashes may differ from the host's.  Re-running install
# regenerates the workspace symlinks so they resolve against the container's
# pnpm store.  --frozen-lockfile ensures no lock changes; --prefer-offline
# avoids network round-trips when packages are already cached in the volume.
