(Libre 2 is a refreshed version of the Libre theme, with more features and added flexibility.)
Libre 2 brings a stylish, classic look to your personal blog or site for longform writing. The main navigation bar stays fixed to the top of the screen while your visitors read, keeping your most important content at hand, while three footer widget areas give your secondary content a comfortable home. Customize Libre 2with a logo or a header image to make it your own.
This could be a good pared-down theme to consider.
