+   ```
+2. Open `/tmp/old.png` and identify its scope:
+   - Header strip: very wide, ≤300 px tall (e.g., 2358×222) → use `ref` of `[data-testid="webui-header"]`
+   - Modal/dialog only: medium, no chrome (e.g., 988×804) → use `ref` of `.ant-modal-wrap .ant-modal` or `[role="dialog"]`

+   - Wizard step / panel: capture the specific panel `ref`, not the layout root

+**Anti-pattern observed in PR #6708**: `header.png` was 2358×222 (header strip) on `main`, recaptured as 2880×1800 (full viewport including sidebar + main content). The filename promised "header" but the new image showed everything. Always run the preflight above before overwriting.
+

+### Match the Existing Screenshot's Framing (for re-captures)
+
+When **replacing an existing screenshot** (same filename), the new image MUST match the previous image's framing scope. The filename encodes a contract about what the image shows.
+
+**Before recapturing**, run the following preflight on the file you intend to replace:
+
+```bash
+# 1. Inspect the previous version's dimensions and visual scope
+git show main:path/to/images/foo.png > /tmp/old.png
+file /tmp/old.png        # note WIDTH x HEIGHT
+# 2. Open /tmp/old.png and identify:
+#    - Is it a header strip? (very wide, very short — e.g., 2358x222)
+#    - Is it a modal/dialog only? (medium, no chrome — e.g., 988x804)
+#    - Is it a sidebar segment? (narrow column — e.g., 1500x1098)
+#    - Is it a full page? (~viewport width × viewport height — e.g., 2880x1800)
+```
+
+Then capture the new screenshot at the **same scope**:
+
+| Old image scope | Capture method |
+|---|---|
+| Header strip (e.g., `header.png`) | `ref` of `header`/top-bar element only — never `fullPage: true` |
+| Modal/dialog only | `ref` of `.ant-modal-wrap .ant-modal` or `[role="dialog"]` |
+| Sidebar segment | `ref` of the sidebar element |
+| Page region (e.g., a step in a wizard) | `ref` of the specific panel, not the whole layout |
+| Full page overview | `fullPage: true` is acceptable |
+
+**Anti-pattern observed in PR #6708**: `header.png` was 2358×222 (header strip only) on `main`, recaptured as 2880×1800 (full viewport including sidebar + main content + breadcrumbs). The filename promises "header" but the new image shows everything. **Always run the preflight above before re-capturing.**
+
+If the framing genuinely needs to change (e.g., the feature now spans more of the page), update the filename to reflect the new scope (e.g., `header.png` → `top_bar_with_session_timer.png`) rather than silently broadening an existing image.

   * AI 가속기: AI 가속기 (GPU 및 NPU)는 기계 학습과 관련된 행렬 / 벡터 계산에 적합합니다. AI 가속기는 훈련 및 인퍼런스 알고리즘을 몇 배나 가속화하여 기계 학습 워크로드의 실행 시간을 몇 주에서 며칠로 줄입니다.
   * 세션: 세션은 지정된 환경과 자원에 따라 생성되는 계산 환경 단위입니다. 이 값을 1보다 큰 값으로 설정하면 위의 자원 설정을 이용한 여러 세션이 지정한 값만큼 동시에 생성됩니다. 세션 시작 요청 시 사용 가능한 자원이 충분하지 않은 경우, 생성하지 못한 세션 시작 요청들은 생성 대기열에 추가됩니다.
