/* Terminal look for the cabinet sections Обзор, Лидеры, Партнёры, Помощь, Настройки (src/pages/Shell.tsx OCTO_SECTIONS).
   Loaded after the cabinet sheets with octo-theme.css, which gives .oc-app the terminal palette.
   Everything is scoped to .oc-app, so other cabinet and site pages keep their look. Values follow octo-terminal.css:
   graphite panels with a 1 px line, Geist 12 to 13 px, 3.84 px corners, 28 to 34 px controls, green accent. */
