            ## 🎫 XLS Number Assignment

            This PR adds a new XLS draft. The next available XLS number has been determined:

            | Draft Directory | Assigned Number | New Directory Name |
            |-----------------|-----------------|-------------------|
            | `${{ steps.assign-number.outputs.draft_dir }}` | **XLS-${{ steps.assign-number.outputs.xls_number }}** | `${{ steps.assign-number.outputs.new_dir_name }}` |

            ### Next Steps for XLS Editors

            Before merging this PR, please:

            1. **Rename the directory** from `${{ steps.assign-number.outputs.draft_dir }}` to `${{ steps.assign-number.outputs.new_dir_name }}`
            2. **Update the preamble** in the README.md:
               - Set `xls:` to `${{ steps.assign-number.outputs.xls_number }}`
               - Set `status:` to `Draft`
