Do's & Don'ts

25 enforceable rules pulled verbatim from the spec

Do
Use Near-Black (`#1c1e21`) for text — not pure black, it's warmer and more readable
Use ui-sans-serif as the primary typeface — it defines the brand personality
Use negative letter-spacing (-1.2px) 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 Steel Blue (`#398ccb`) 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
Keep navigation sticky to the top — the design uses a persistent navigation pattern
Maintain nav height at 60px — consistent vertical space for the navigation bar
Respect the 4px–32px spacing range — the design uses a wide scale for visual breathing room
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
Make the navigation sticky — it stays visible during scroll, signaling content depth
Include a theme toggle in the nav — dark mode is a first-class feature
Each card uses an icon (not photo) — the visual language is illustrative, not photographic
Use a 4-column grid on desktop — density matters for this content type
Lay out testimonials in a grid (13+ items) — quantity signals scale and trust
Don't
Don't use pure black (`#000000`) for text — the near-black adds warmth
Don't substitute with generic sans-serif or serif — the custom font carries the brand
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 collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence
Don't put a CTA button in the nav — this design uses links only at the top
