How to keep the text color in the Yandex.mail night theme?

Question

Layout of letters

When laying out emails, the task arose to preserve the color of the text in the night theme of Yandex.mail. Since Yandex.Mail does not support media queries, the options to set styles for the night theme @media {prefers-color-scheme: dark}do not work. The variant with setting the text color with !importantalso does not work, the variant of the text with an image is also not suitable. Are there any working options?
