/* ============================================================
   Портфолио Артёма Рябова.
   Язык тот же, что у демо-макетов, которые уходят клиентам: широкий шрифт,
   плитки, одна анимация со смыслом. Владелец жмёт «Хочу такой сайт» на
   макете и попадает сюда — в тот же стиль, только крупнее.
   За всем — тёмные грани на Three.js (scene.js).
