   КАК НАСТРОИТЬ ШАБЛОН ПОД СЕБЯ (меняйте ТОЛЬКО этот блок):

   1) ОСНОВНОЙ ЦВЕТ  — замените --color-primary и --color-primary-dark
      (все кнопки, ссылки, иконки, hover-эффекты перекрасятся сами).
   2) ШРИФТЫ         — замените --font-heading и --font-body.
      ВАЖНО: новый шрифт нужно также подключить тегом <link> в <head>
      всех страниц (найдите комментарий "FONTS" в HTML).
   3) РАЗМЕР ТЕКСТА  --fs-base задаёт базовый размер; заголовки
      считаются от него (clamp), поэтому вёрстка не ломается.
      Меняйте значения на +-10..15% и всё останется аккуратным.

   Остальные переменные — второстепенные, тоже можно менять.
