/* ============================================================
 * scm-bulk-upload-modal — 일괄 업로드 모달
 * ------------------------------------------------------------
 * 1024w 큰 모달. header / body (warning + type-section + history) /
 * footer 구조. 자체 backdrop 포함.
 *
 * Marker:
 *   <div class="scm-bu-backdrop"></div>
 *   <div class="scm-bu-modal" role="dialog">
 *     <header class="scm-bu-header">...</header>
 *     <div class="scm-bu-body">
 *       <div class="scm-bu-warning">...</div>
 *       <div class="scm-bu-type-section">...</div>
 *       <section class="scm-bu-history-section">...</section>
 *     </div>
 *     <footer class="scm-bu-footer">...</footer>
 *   </div>
 *
 * 자체 내부 컴포넌트:
 *   - scm-bu-warning (collapsible 주의사항)
 *   - scm-bu-type-section (업로드 유형 선택)
 *   - scm-bu-history-table (요청 이력 테이블)
 *
 * 외부 모듈 활용:
 *   - 라디오: scm-radio + .scm-radio-dot (Stage 2)
 *   - 셀렉트: scm-select scm-select--bu (Stage 2)
 *   - 버튼: scm-button (Stage 2)
 *
 * 단, 본 파일은 자가포함성을 위해 bu-radio / bu-select / bu-btn
 * legacy 시각도 자체 클래스로 그대로 보존. 추후 외부 모듈로
 * 100% 이전 가능.
