/* ============================================================================
   Settings page (/settings) — "Mail / WhatsApp Settings"
   ----------------------------------------------------------------------------
   WHY THIS FILE IS GLOBAL AND NOT A SCOPED .razor.css
   ---------------------------------------------------
   The app shell is built for SmartGrid screens, which scroll *inside* themselves:

       .page-body-wrapper   height: calc(100vh - 2px);  overflow: hidden   (appV.css)
         .page-body         height: calc(100vh - 65px); overflow: hidden   (appV/app.css)
           .root-container  height: 100%                                   (appV.css)

   Every one of those clips. A page hosted in there can only scroll if it builds an
   unbroken chain of height:100% + flex-grow + min-height:0 down to a single
   overflow:auto pane — and if ANY link in that chain breaks, nothing scrolls and
   no scrollbar appears; the content is just silently cut off. That is exactly what
   kept happening here, because the settings markup added four more overflow:hidden
   links of its own on top of the shell's three.

   So this page opts OUT of that model: `:has(.settings-page)` turns the shell's
   clipping ancestors back into a normal scrolling document for this route only,
   and the page content below flows at its natural height. One scroller, no chain
   to break. Those ancestor rules cannot live in a scoped .razor.css — Blazor
   rewrites scoped selectors with the component's `[b-xxxxx]` attribute, which the
   shell elements do not carry — hence a plain stylesheet, loaded from App.razor.
