   این فایل پایه بصری هر چهار صفحه پنل است: ورود، پنل عضو، پنل مدیریت،
   سیستم لاگ و صفحه ساختار فمیلی.

   ساختار:
     ۱. توکن‌ها (رنگ، فاصله، تایپوگرافی، شعاع، سایه، حرکت)
     ۲. پایه و ریست
     ۳. پس‌زمینه صحنه
     ۴. سطوح و کارت‌ها
     ۵. تایپوگرافی
     ۶. دکمه‌ها
     ۷. فرم‌ها
     ۸. نشان‌ها و وضعیت‌ها
     ۹. مودال‌ها
     ۱۰. توست‌ها
     ۱۱. حالت خالی / اسکلت بارگذاری
     ۱۲. کمکی‌ها و دسترسی‌پذیری
