 【已完成】
+   - V10.190 補 `/observability/ppt_audit_file/<filename>` 站內線上預覽：PPTX 由 LibreOffice 轉 PDF 快取後以 iframe 預覽，保留原始 PPTX 下載；Dockerfile 加 `libreoffice-impress`，compose 預設啟用 `PPT_VISION_ENABLED=true`，PPT 產線頁新增視覺 QA 停用原因與更精簡的控制台式排版。
+   - V10.188 補強 `/observability/ppt_audit_history` PPT 視覺 QA 產線：頁面明確呈現每日、每週、每月、每季、每半年、每年定期產出節奏，並顯示 `ppt_generation_runs` DB 寫入紀錄；保留自動補齊缺漏與資料庫/檔案覆蓋狀態。
    - V10.187 修正 `/daily_sales`、`/growth_analysis` 圖表空白：Chart JSON 改從 `<template>.content.textContent` 讀取，補空資料診斷狀態；成長分析改用 realtime 明細新鮮度覆蓋過期月結摘要，並為 growth cache 加入資料指紋。
    - V10.151 接續前端 V3 全站 UI/UX：廠商缺貨 `/vendor-stockout/vendor-management`、`/vendor-stockout/send-email`、`/vendor-stockout/history` 改走新版 `ewoooc_base.html` shell 與 `page-vendor-tools.css`，移除舊紫藍 navbar/live route。
    - V10.151 補 `/abc_analysis/detail` 新版 ABC 詳情頁與安全 loading state，移除 raw HTML fallback，資料表維持正式快取資料來源與匯出連結。
