Use 6px border-radius on cards — consistent with the grid card corners
Style form inputs with a `1px solid rgb(193, 193, 193)` 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 substitute with generic sans-serif or serif — the custom font carries the brand
Don't invent new shadow values — use only the extracted shadow levels
Don't apply pill radius on rectangular buttons or cards — it's reserved for specific interactive elements
Don't introduce additional saturated accent colors — the palette is intentionally controlled
Don't use rectangular buttons for primary actions — the rounded pill shape is the brand standard
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
Don't over-build the footer — this design keeps it minimal (1 cols, 0 links)
