/* GGNTU Transfer — оформление.
   Стиль: кибернетический «приборный» интерфейс (HUD) в духе Flipper Zero —
   тёмный фон с сеткой и сканлайнами, угловые скобки у панелей, моноширинные
   технические подписи, неоновое свечение акцента — на фирменном малиновом
   ggntuhomeworker (#b31b1b). Тема по умолчанию тёмная; светлая — через
   data-theme на <html>. Шрифты системные (без внешних CDN). */
