/* ============================================================
   RADITONE AUTH
   ظاهر صفحه ورود / ثبت‌نام / فراموشی رمز

   نکتهٔ مهم: در این فایل هیچ رنگی ثابت نوشته نشده است. تمام رنگ‌ها از
   متغیرهایی می‌آیند که PHP آن‌ها را از تنظیمات قالب پر می‌کند
   (`raditone-auth-vars` در my-account.php). بنابراین تغییر رنگ‌ها از
   پیشخوان، بدون دست‌زدن به CSS، روی این صفحه هم اعمال می‌شود.

   حالت روشن/تاریک را مدیر از تنظیمات قالب انتخاب می‌کند
   (`auth_theme_mode`) و کاربر امکان تغییر آن را ندارد؛ به همین دلیل هیچ
   کلاس یا صفت وابسته به localStorage اینجا وجود ندارد.
   ============================================================ */

/* ============================================================
   متغیرهای پایه (fallback)
   فقط وقتی استفاده می‌شوند که بلوک PHP در صفحه نبوده باشد
