DeepL rebound for Andreas

Small UI practice 🙂

Made some changes for Andreas' option:
1. Everything has AAA contrast and perfect readability.
2. Better language selection with big click area.
3. Little element reorder to keep branding and stabilize composition.

Needs work:
1. Input and result styles. Struggle to get right inner shadow. Any tips?
2. Background and input contrast colors. Trying to make it simpler, but easier to look at. Thinking about filling the whole thing with contrast blue color.
