   Dialog Theme — Dark Fantasy (matches TowerView palette)
   ───────────────────────────────────────────────────────────────
   Applied to MudBlazor dialogs via DialogOptions.BackgroundClass so
   the Phase 3 dashboard modals (ChestOpenModal, AscenderPickerModal,
   plus any future modal that needs the same look) inherit the
   tower's dark-blue + gold palette instead of MudBlazor's default
   white card.

   IMPORTANT — MudBlazor 8 DOM
   ──────────────────────────────────────────────────────────────
   In v8 `DialogOptions.BackgroundClass` is applied to the
   <MudOverlay> sibling of <div class="mud-dialog">, NOT an
   ancestor of it. The actual rendered structure is:

     <div class="mud-dialog-container ...">
       <div class="mud-overlay ... asc-dialog-theme">
         <div class="mud-overlay-scrim ..."></div>
       </div>
       <div class="mud-dialog ...">                <!-- sibling -->
         <div class="mud-dialog-title">...</div>
         <div class="mud-dialog-content">...</div>
         <div class="mud-dialog-actions">...</div>
       </div>
     </div>

   So we reach the dialog surface from the themed overlay using the
   general sibling combinator (`~`). A descendant selector
   (`.asc-dialog-theme .mud-dialog`) silently matches nothing — that
   was the bug in the first version.

   Color tokens are duplicated from src/Presentation/Ascend.Web/
   wwwroot/css/pages/tower-view.css (the .asc-tower-view --tw-*
   tokens are scoped to that selector, so they aren't visible
   inside MudBlazor's portal-rendered dialog).
