/* ==========================================================================
   驗證摘要（asp-validation-summary）
   ==========================================================================
   🔴 ASP.NET 的慣例：無錯誤時容器帶 .validation-summary-valid，有錯誤時換成
   .validation-summary-errors。標準 MVC 範本的 site.css 內建「-valid 就隱藏」這條規則，
   本專案原本沒有，所以各頁改用內聯 style="display:none" 自行遮蔽。

   內聯樣式擋不住別的腳本：notification-system.js 會把頁面上每個 .alert 當成通知組件處理，
   而 jQuery unobtrusive 在 summary="All" 模式下會預先注入一個空的佔位 <li>，
   讓「有 <li> 就 show()」這類判斷誤判成有錯誤，一 show() 內聯樣式就沒了
   ⇒ 常駐一條沒有內容的「操作失敗」紅色橫幅（實際發生過）。

   改用 class 驅動：class 由框架維護（伺服器端渲染 + unobtrusive 於用戶端切換），
   任何腳本改內聯 display 都蓋不過它。有錯誤時 class 變成 -errors，本規則自然不再適用。 */
