Sending this theme to upstream

[archisman-panigrahi]

Hi, I like this theme very much, and I would like this theme to be a part of default Foliate (if the developer of Foliate agrees). Would you mind if I open an issue in the Foliate Github repo to include this theme?

Why: Because then the theme would be easier to set up, and would reach an wider audience (since most Foliate users don't know about the existence of this theme).
