# check-remove-cleanup.sh — 驗**使用者真的會走的那條路**：
# 從各庫頁按「移除」→ 對話框 → 勾「順便清掉」→ 看到清單 → 按確定（arcrun-rag#138）。
#
# 🔴 為什麼要這一支：Go 那邊的迴歸網只證明「函式做對事」，證明不了
#    「按鈕存在、清單真的攤出來、第四個參數真的傳下去」。#138 的驗收條件裡
#    「使用者要能在動手前看到將要刪掉哪些東西」**只有前端驗得到**。
#    （同 check-render.sh 的理由：改完 UI 不准拿沒看過的畫面交件。）
#
# 做法沿用 check-render.sh：把 dist 複製到暫存、插一支 mock.js 假扮 window.go，
# 再用 headless Chrome 真的載入、真的點下去，最後 --dump-dom 讀結果。
