Create a fun dark mode toggle

[adriaandotcom]

For example: https://github.com/JoseRFelix/react-toggle-dark-mode

Or https://github.com/heisenberg-ayush/svg_Morphing_Animation (demo)

We would also need a middle state saying "auto" for when we want to follow the system settings.

Other resources:

• https://github.com/shubhamhackz/light_dark_toggle
• https://github.com/cawfree/react-dark-mode-toggle

Maybe svgator.com could help.
