## Rules
DO:

- Maintain Railway's aesthetic: Dark and electric purple — instant infrastructure with indie-developer energy.
- Apply 4px base-unit spacing throughout
- Use Inter for all text elements
- Meet WCAG AA contrast (4.5:1 minimum for body text)

DON'T:
- Invent colors outside the defined palette
- Use system-default blue (#0000EE) for links — use var(--color-primary)
- Apply border-radius values not on the brand scale
- Use font-weight below 400 or above 900
