/*
  NET CHEBURNET — таблица стилей.

  Принцип: ни одной декоративной детали, которая не несёт смысла. Цветом
  выделяется только состояние (активна / истекает / заблокирована), всё
  остальное живёт на трёх оттенках серого и типографике. Тёмная тема —
  основная, светлая поддержана через prefers-color-scheme.
