   Firefox 121+ — ~90% browser support). Browsers without :has()

   Blazor Server reconnect modal (custom, see App.razor #components-reconnect-modal)

     .components-reconnect-rejected - server reached but circuit is gone (reload)

   then fades in. Tab-switch / background-tab drops recover in well under a
   second, so they never reach the fade-in and no banner flashes. Only an outage
