/* issue 367 場景 netskope-issue-sim：Netskope 10 大議題的互動模擬（路徑型與整併型）。深色面板，顏色全走 token。
   版面用容器查詢：面板寬 ≥ 62rem 時右側是檢視面板（所選節點、逐關紀錄），否則排在下方；流程圖在主欄寬 ≥ 40rem 時橫排，窄螢幕直排（從 320px 起不橫向溢出）。
   狀態不只靠顏色：被擋＝✕ 徽章加紅框、放行＝✓、外洩／警示＝! 徽章；路徑線型也不同（實線＝已放行、粗虛線＝可被利用、細虛線＝已看見）。
   沒有 JS：只顯示 .nis-static（控制點說明與預設情境）；JS 成功後加 is-live，改顯示 .nis-app。動畫只動 transform／opacity 與背景，減少動態或 data-motion=off 時全部關閉。 */
