  Расхождение с апстримом: `IconPlaceholder` заменена инлайновым `<svg>`
  (lucide-react v0.545.0 "chevrons-up-down"/"check"/"plus"/"settings") —
  см. docs/PORTING.md §5. Логотипы Anthropic/Claude — уже инлайновый
  `<svg>` в оригинале, перенесены без изменений; сетевое изображение
  unsplash (третий workspace, только в закрытом состоянии не рендерится)
