📄 Context

Here are the home page changes on colour, skin tones and fonts in Light mode to comply with the new Cartesi brand. The application's structure did not change, only the look and feel.

PS: Refer to the parent of this issue for references on colours, fonts and the overall look and feel of a page. PS²: Don't worry about the header and footer, because that is addressed in a separate issue #82
