OpenAI Codex submitted a fix so the Bun CSS bundler removes leading @layer statements when filtering leading directives. The change spans two files, with 42 additions and one deletion in one commit, and adds a regression test. The local test run failed because CMake configuration requires network access. It closed unmerged after human review.
