/* ── Стилі сторінок кейсів ──────────────────────────────────────────────
   Один файл на всі сторінки /keysy/ — навмисно зовнішній, а не інлайн:
   дизайн тут ще перероблятиметься, і зручніше правити в одному місці,
   ніж у чотирьох копіях. Кешується між сторінками кейсів.
   Блок шрифтів і сабсет Font Awesome підклеєні знизу — той самий, що на
   головній. ⚠ Береш нову fa-* іконку — перезбирай сабсет, інакше буде
   порожній квадрат (перевірка: ширина гліфа != ширина фолбеку).
