12 enforceable rules pulled verbatim from the spec
Do
Use the extracted shadow patterns for elevation — they are tuned to match the brand palette
Use Off-White (`#efefef`) as the primary accent — it's the brand's signature interactive color
Use small 4px radius for buttons — this design system uses subtle rounding, not pill shapes
Style form inputs with a `2px inset rgb(118, 118, 118)` border — use border-based inputs, not floating labels or underline-only
Respect the 4px–32px spacing range — the design uses a wide scale for visual breathing room
Each card includes a left image — imagery is part of the card identity, not optional
Don't
Don't invent new shadow values — use only the extracted shadow levels
Don't introduce additional saturated accent colors — the palette is intentionally controlled
Don't over-round buttons with pill or large radius — the system uses restrained, sharp-ish corners
Don't remove the input border — the border is the primary affordance indicator for form fields
Don't make the nav sticky — this design lets it scroll away to maximize content focus
Don't put a CTA button in the nav — this design uses links only at the top
