/* AI Market Club v4 - визуал бренда AI Market Lab (рилсы r10b): светлая база #FAF7F4, графит точечно,
   радужная кромка - подпись бренда (кнопка, кольцо кнопки-отправить, бегунок табов, плашка, карточка цены),
   радужный график роста на первом экране. Цвета радуги - только линии, кромки, заливки, не текст.
   Шрифт Inter Tight 500/600/650, локально (те же файлы, что rolik3/fonts). */
