/* ═══════════════════════════════════════════════════════════════════════════
   Task management — page, kanban card, create/detail dialogs.
   Prefix: mw-tk-*
   Visual identity: a self-contained dark "ops board" theme (independent of the
   app-wide light/dark toggle), matching docs/mockups/task-management.html.
   Applied via local --mud-palette-* overrides on .mw-tk-page / .mw-tk-dialog so
   MwDataGrid, MwKanbanBoard, and stock MudBlazor components re-skin themselves
   with zero changes to their own code — only variables are overridden here.
