# Design System: MongoDB — Do's and Don'ts

## Do

- Use `#001e2b` (forest-black) for dark sections — not pure black
- Apply MongoDB Green (`#00ed64`) sparingly for maximum electric impact
- Use MongoDB Value Serif ONLY for hero/display headings — Euclid Circular A for everything else
- Apply Source Code Pro uppercase with wide tracking (1px–3px) for technical labels
- Use teal-tinted shadows (`rgba(0,30,43,0.12)`) for primary card elevation
- Maintain the dark/light section duality — dramatic contrast between modes
- Use weight 300 for body text — the light weight is the readable voice
- Apply pill radius (100px) to primary action buttons

## Don't

- Don't use pure black (`#000000`) for dark backgrounds — always use teal-black (`#001e2b`)
- Don't use MongoDB Green (`#00ed64`) on backgrounds — it's an accent for text, underlines, and small highlights
- Don't use standard gray shadows — always use teal-tinted (`rgba(0,30,43,...)`)
- Don't apply serif font to body text — MongoDB Value Serif is hero-only
- Don't use narrow letter-spacing on Source Code Pro labels — the wide tracking IS the identity
- Don't mix dark and light section treatments within the same section
- Don't use warm colors — the palette is strictly cool (teal, green, blue)
- Don't forget the green accent underlines — they're the signature decorative element
