## About the changes
Creating the first version of the Dark theme
Refactor: colors variables
Refactor: use theme variable instead
- this change will help us to use MuiCssBaseline, and we can use classes
directly for easy customization when we can't identify MUI classes
Refactor: adjusting some files components
- i’ve touched also the structure of some files, not only the colors
variables (but only to adjust the style, not functionality)
Fix: dark mode persistence on refresh (by Nuno)
Feat: dark mode sees light logos, and light mode sees dark logos (by
Nuno)
