/* LỊCH SỬ (gỡ 2026-07-17) — rule này từng là:
       .d-flex.gap-2 > .mud-button-root            { flex: 1 1 0; white-space: nowrap; }
       .d-flex.gap-2 > .mud-button-root:first-child:last-child { flex: 0 1 auto; }
   dưới tiêu đề "Filter Bar Button Equal Width".
   VÌ SAO GỠ PHẦN flex:
   1. Filter bar KHÔNG còn dùng nó. Bản viết lại §6 (2026-05-06) cho filter bar class riêng, và
      `.page-toolbar .tb-actions` (dưới file này) đã tự cấp `display:flex; gap:8px` + `min-width:90px`.
      Không file nào có class chứa cả `tb-actions` lẫn `gap-2` → rule là HOÁ THẠCH, phục vụ 0 thứ nó nói.
   2. Nhưng selector `.d-flex.gap-2` là GLOBAL: MudStack Row Spacing="2" render đúng class đó
      → rule kéo giãn nút ở **38 chỗ** (123 MudStack + 76 div literal, quét 2026-07-17). Rà cả 38: **0 chỗ
      muốn nút bằng nhau**; 6 chỗ có bằng chứng NGƯỢC — tác giả đặt `flex:1` cho phần tử khác
      (MaintenanceChecklistPanel:16 thanh tiến độ bị bóp còn 1/3; KnowledgeBasePage:200 /
      ScadaImagePickerDialog:16 / ScadaFaceplateParamsDialog:21 ô nhập; RevealSecretDialog:46) hoặc đặt
      <MudSpacer/> sau nút (EnergyBudgetBatchDialog:46, WaterBudgetBatchDialog:50) — MudSpacer chỉ có
      nghĩa khi nút giữ bề rộng tự nhiên.
   3. ⚠️ `:first-child:last-child` KHÔNG cứu được "nút đơn độc" như tưởng — nó nghĩa là CON DUY NHẤT của
      container. Nút đứng cạnh MudText/MudSelect/MudFileUpload vẫn dính. Đó là lý do bề mặt là 38 chứ không phải 10.
   GIỮ LẠI `white-space: nowrap`: nó nằm trong chính rule cũ và MudBlazor KHÔNG cấp lại từ đâu
   (đã verify MudBlazor.min.css 9.4.0) → gỡ trọn thì nhãn nhiều từ xuống 2 dòng.
   ⇒ MUỐN nút bằng nhau ở 1 chỗ cụ thể: đặt `style="flex:1"` TẠI CHỖ ĐÓ. ĐỪNG dựng lại rule global. */
