 * B09_Estimation_UI_Shell.ts
 * 로그인 후 09: 6차 워크플로우 (원가계산) — 화면 **틀** (PLAN 12장 · 2026-09-14 브레인 판정)
 *
 *   - 틀은 탭 줄과 등록만. 탭마다 파일 하나(`B09_Estimation_UI_Tab_<이름>.ts`) — 계약은 `_Shell_Types`.
 *   - ⚠ 등록 권한 = 랩탑_서브. 다른 창은 탭 파일을 만들고 이름을 알려 등록을 부탁함.
 *   - 탭을 고를 때마다 본문·좌측 칸을 비우고 `render(ctx, arg)`. `ctx.open(key, arg)` = 다른 탭으로 들어가기.
