   B13 Flasher — flasher.b13.ltd
   Дизайн-система «Pro Graphite» (тёмная) / «Aluminium» (светлая).
   Продолжение настольного B13 Flasher (lib/ui/theme.py).

   Правила цвета:
   - красный B13 только там, где пишут в машину (.btn-write, статус Writing);
   - зелёный — ок/активно, янтарный — предупреждение/ожидание, синий — инфо;
   - всё остальное — графит, тонкие линии, много воздуха.

   Тема переключается атрибутом data-theme="light" на <html>; без атрибута — тёмная.
