   DISIPHEE — صفحه‌ی آکادمی

   این صفحه عمداً مثل وبلاگ چیده نشده. سلسله‌مراتب صفحه از
   فلسفه‌ی آموزش‌ها می‌آید: Knowledge → Understanding → Action.

   وزن بصری بیشترین جا را به «مسیرهای یادگیری» می‌دهد، چون
   همان بخشی است که کاربر را از خواندن به انجام دادن می‌برد.

   یادداشت برند: بدون گرادیان، بدون درخشش، بدون سایه.
   فقط پالت رسمی و متغیرهای مشترک سایت.
