  Live Playbook Sessions Design System: component styles
  TODO: VERIFY. The system's project/components/bundle.css could not be read during the build.
  This file reconstructs the documented class names (efi-*) from the brief's fallback summary.
  Replace it with the real bundle.css, then re-run the test checklist in README.md.
