[Tracking] Design system (styles and standards)

[luxaritas]

Tracking for high-level design system decisions. This includes:

• [ ] #30
• [ ] #31
• [ ] #32
• [ ] #33
• [ ] #34
• [ ] #35
• [x] #36

Once the standards are set, we also need to implement these as helpers where possible:

• [x] #37
• [x] #38
• [x] #39
• [ ] #40
