      # node_modules also keys on the lockfile hash: a sticky disk is a mutable
      # volume, and `bun install --frozen-lockfile` adds what the lockfile needs
      # without pruning what it dropped, so branches on different lockfiles were
      # contaminating each other (a stale @next/swc 16.2.6 outlived the 16.2.11
      # bump). The bun and Turbo caches are content/hash-addressed, so they stay
      # shared — that is what keeps a fresh node_modules disk cheap to fill.
