## Rules
DO:

- Maintain Docker's aesthetic: Clean and reliable blue — containerization made trustworthy and enterprise-ready.
- Apply 4px base-unit spacing throughout
- Use Open Sans 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
