   Масштаб. Как в исходной вёрстке Tilda, макет пропорционально
   масштабируется вместе с шириной окна:
     • мобильная сетка — 360px, десктопная — 1280px;
     • 1rem = 10px макета, т.е. «14px из макета» = 1.4rem.
   Координаты элементов композиций берутся прямо из макета:
     style="--x:273; --y:388; --w:409"   — десктоп (сетка 1280)
     style="--mx:10; --my:224; --mw:300" — мобильная версия (сетка 360)
