/* Перерасчёт пенсии — лендинг
   Direction: «справка из ведомства» — строгая бумажная сетка, тонкие линейки,
   крупная читаемая типографика (аудитория 60+), один зелёный акцент без скруглений.
   Палитра: холодная зелень (бумага #eef1ef, чернила #0e1a2b), акцент — тёмная зелень 165°.
   Никаких иллюстраций и эмодзи-иконок: только типографика, линейки и числа. */
