17 enforceable rules pulled verbatim from the spec
Do
Use Off-White (`#f0f0f0`) as the page background — it's intentionally not pure white
Use negative letter-spacing (-1.68px) at display sizes for compressed, editorial headlines
Use the extracted shadow patterns for elevation — they are tuned to match the brand palette
Use full-pill radius (9999px) only for specific elements (avatars, pills, toggles)
Use Primary (`#1c1c1e`) as the primary accent — it's the brand's signature interactive color
Use 8px border-radius on buttons — the standard corner rounding for interactive elements
Style form inputs with a `1px solid rgb(233, 234, 239)` 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 top image — imagery is part of the card identity, not optional
Don't
Don't use pure white (`#ffffff`) as a page background — the warm tone is part of the brand identity
Don't increase letter-spacing on headings — the type is designed to run tight at scale
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 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
