 ## Кнопки
 - Все кнопки без жёсткого outline.
+- Текстовые кнопки в модалках не сжимают текст:
+  - минимальный горизонтальный отступ от текста до края кнопки: `10px`
+  - для CTA предпочтительно использовать общий padding `1.25rem` или больше
+  - текст не должен визуально прилипать к радиусу кнопки
 - Primary button:
   - фон: акцентный или `active_card_rgb`
   - текст: определяется автоматически по контрасту заливки

   - круг на мягком `white/10`
   - без внешнего outline и без синей browser-рамки
 - Текстовый статус рядом с checker может дублировать состояние, но сам визуальный якорь должен оставаться круглым, а не квадратным checkbox.
+- В деталях задачи структурные блоки создаются из меню `Добавить подэлемент` прямо в карточке, без отдельной модалки:
+  - порядок меню: `Создать текстовый блок`, `Создать чекер`, `Создать новую подзадачу`, `Добавить существующую подзадачу`
+  - текстовый блок содержит два поля: необязательный заголовок и текст
+  - чекер отображается без внешней подложки и без заголовка: только строки с круглым checker-якорем и plus-зона добавления строки
+  - первые 10 строк чекера видны сразу, дальше включается внутренний скролл списка
+  - у каждого структурного блока справа есть меню `...` с удалением блока
+  - блок хранится в штатном JSON-поле задачи `detail_layout`, а не в `description_html`: описание проходит HTML-sanitizer и не должно нести layout-состояние
+  - `detail_layout` является частью самой задачи, поэтому кастомные поля мультиплеерны и восстанавливаются после закрытия/повторного открытия карточки
 
 ## Toolbar и верхние панели
 - Элементы верхней панели центрируются по одной горизонтальной оси.
