   Фонд · Читалка · Студия атомов знаний встык на сплиттерах Workbench (workbench.css).
   Слой ПОВЕРХ app_v2.css / screens.css / workbench.css / organizer.css: переиспользует tk-side-tabs, segmented,
   df-bar, db-pop, studio-device/phone-*/studio-msg и добавляет только своё (kb3-*). В компонентах — только var(...).
   Откат — убрать <link> в index.html (и вернуть kb.js из _backup/20261015-kb3col/).
