Code Review

This pull request removes the "Junkie" and "Memberberry" themes and introduces several popular color schemes, including Dracula, Solarized (Dark and Light), Gruvbox, Nord, Monokai, One Dark, Tokyo Night, and Synthwave '84. The changes update the localization files, the settings store, and the theme utility definitions. Feedback was provided regarding the Solarized Light theme, specifically noting that the button text colors have insufficient contrast against the background, which may impact accessibility.

[gemini-code-assist]

The buttonText and buttonTextSecondary colors in the SolarizedLight theme have insufficient contrast against the buttonBackground (#B58900, a yellow/orange color). Using a light color like #FDF6E3 (Base3) for text on a yellow background results in a low contrast ratio, which can impact readability and accessibility. Consider using a darker color from the Solarized palette, such as #002B36 (Base03) or #586E75 (Base01), for better visibility.
