     Инлайновый SVG вместо иконочного шрифта @tabler/icons-webfont, который
     грузился с CDN и блокировал первую отрисовку. Размер наследуется от
     font-size родителя — ровно так же, как вёл себя шрифт, поэтому все
     существующие правила (.nav-icon, .guide-genre-icon, .create-upsell__icon)
     продолжают задавать размер через font-size без изменений.
