15 enforceable rules pulled verbatim from the spec
Do
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 Pure White (`#ffffff`) as the primary accent — it's the brand's signature interactive color
Use 6px border-radius on buttons — the standard corner rounding for interactive elements
Style form inputs with a `1px solid rgb(228, 228, 231)` border — use border-based inputs, not floating labels or underline-only
Make the hero full-viewport (≥70% screen height) — this design uses an immersive hero, not a tall navbar
Include exactly 3 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose
Lay out testimonials in a grid (4+ items) — quantity signals scale and trust
Include a newsletter signup in the footer — email capture is part of the conversion funnel
Don't
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
