   KVATASK SITE — MOCKUPS
   Embedded HTML/CSS-копии реальных компонентов продукта.
   Все классы с префиксом .mu-* чтобы НИКОГДА не пересечься
   с продуктовыми классами static/css/*.css.

   Каждый мокап имеет атрибут data-mu-mode на корне:
     data-mu-mode="static"  — нынешний режим, inline-разметка.
     data-mu-mode="live"    — будущий режим, JS подменит содержимое
                              реальными данными. CSS не меняется.
