         2. 調整直線軸承詢價邏輯，當上傳圖面時預設型號為「客製化直線運動軸承」，並強制要求上傳圖面後始得加入詢價單

版本: 8.11
日期: 2026/08/17
修改摘要: 1. 修正對刀儀規則引擎 evaluateRules 中的全局 DOM 查詢（.option-pill 與 .spec-group），將其嚴格限制於 #panel-tool-setter 容器內，修復預設將定位開關選項灰階停用以及預設劃掉對刀儀「手動」量測方式之問題
         2. 修復定位開關頁面因全局查詢干擾而導致初始化時非預期自動勾選「IP67」之 Bug

版本: 8.12
日期: 2026/08/17
修改摘要: 1. 調整 handleFormSubmit 表單提交函式，利用 fetch 以 POST JSON 方式將詢價單資料異步傳送至遠端 API https://mes.t-sense.tw/accept_inquery.php
         2. 加入提交防重複點擊禁用狀態與錯誤處理提示

版本: 8.13
日期: 2026/08/17
修改摘要: 1. 新增全域變數 uploadedDrawingData 用以儲存直線軸承圖檔之 Base64 編碼
         2. 修改 handleBearingFile 以 FileReader 將檔案非同步轉換為 Data URL Base64 格式
         3. 調整 clearBearingUploadedFile 與 addLinearBearingToCart，於加入購物車時附帶 drawingData Base64 內容並於清空時同步釋放，完成附檔傳輸整合

版本: 8.14
日期: 2026/08/18

         2. 實作以「適用導柱外徑 (φ3mm ~ φ50mm)」為起點的動態規格 Pills 渲染及防呆選取控制
         3. 整合加購功能 addBallCageToCart()，支援選定之標準鋼珠套參數格式化寫入詢價購物車中

版本: 8.15
日期: 2026/08/18
修改摘要: 1. 於常見鋼珠套「鋼珠直徑」規格標題旁新增「適用導套內徑」提示徽章 (ball-cage-sleeve-id-badge)
         2. 實作自動計算邏輯 updateBallCageSleeveID()，套用公式「導套內徑 = 導柱外徑 + 2 * 鋼珠直徑」，當此二欄位均選取時動態計算並展示，加購或重置時自動收合隱藏

版本: 8.16
日期: 2026/08/18
修改摘要: 1. 於常見鋼珠套標題右側新增「重置選擇」按鈕
         2. 實作 resetBallCageConfigurator() 函式，並在點擊重置按鈕或加購成功時呼叫以將選取面板狀態完整重設與隱藏
