/* Лендинг «Тепловые насосы для бассейна». Только эта страница; всё под .hp — шапка и подвал сайта не задеты.
   Язык цвета — тепловизор: синий = холод (воздух, фреон до компрессора), пурпур = горячий газ, янтарь = тепло в
   воде. Цвет тепла — только там, где он что-то значит (температура, нагрев, прогресс чтения).
   Шрифт: data-font="own" — Unbounded (заголовки, крупные числа) + Golos Text (текст); "site" — шрифт сайта.
   Движение — только при prefers-reduced-motion: no-preference и когда скрипт поставил .hp-js. */
