Локальные _StatTile/_ChartCard заменены на общие StatTile/SectionCard, блоки капитала/месяца/инвестиций получили SectionHeader, ряды плиток переведены с Wrap на TileCarousel. Заодно цвет «ок» в чипе качества данных переведён с хардкод Colors.green на ChartColors.slot3Aqua — тот же цвет, что signColor уже использует для положительного знака.
