/* ============================================================
   notification.css — اعلان درون‌برنامه‌ای (Navy / Teal)
   ============================================================

   ⚠️ نکته معماری: پنل اعلان با position:fixed و bottom:20px تعریف
   شده تا از پایین صفحه باز شود. هرگز داخل appbar قرار ندهید — چون
   backdrop-filter برای عناصر position:fixed یک containing block
   می‌سازد و bottom نسبت به appbar محاسبه می‌شود.
