[FEATURE] When using Classic mode for Now Playing, use dynamic font color.

[zhusun890]

Hello! Thanks for the application, it's really wonderful.

I’d like to request a new feature that could improve the user experience. When using Classic mode for the Now Playing display, and setting the Artwork Shadow to Use Accent Color and fill the whole bar, the font color becomes difficult to read in certain conditions.

In Dark mode, the text is usually white, which blends in poorly with lighter artwork. In Light mode, the text is black, which is hard to read with darker artwork. It would be even better if the app could dynamically adjust the font color based on the artwork's brightness, ensuring the text is always readable regardless of the background.
