rendu réel · source de vérité

expo.dev is built on a soft, near-white canvas (rgb(252, 252, 253)). The system uses rgb(48, 164, 108) as the accent for primary actions and brand signals. Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside Inter as the primary typeface. A layered elevation system (7 distinct shadows) building a clear front-to-back hierarchy. Motion is a first-class concern — 24 keyframe animations plus transition-driven interactions.

Do's & Don'ts

25 enforceable rules pulled verbatim from the spec

Use Pure White (`#fcfcfd`) as the page background — it's intentionally not pure white

Use Near-Black (`#1c2024`) for text — not pure black, it's warmer and more readable

Use Inter as the primary typeface — it defines the brand personality

Use negative letter-spacing (-3px) 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 Teal (`#30a46c`) as the primary accent — it's the brand's signature interactive color

Use 24px border-radius on primary buttons — the brand uses generously-rounded CTAs

Use 20px border-radius on cards — consistent with the grid card corners

Maintain nav height at 68px — consistent vertical space for the navigation bar

Respect the 4px–48px 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 5 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose

Repeat the primary CTA across 2 banner sections — conversion paths are layered, not single

Build a content-dense footer (5 columns, ~42 links) — this site treats the footer as a sitemap, not an afterthought

Don't

Don't use pure white (`#ffffff`) as a page background — the warm tone is part of the brand identity

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 use sharp-cornered or pill buttons — 24px is the CTA border-radius standard

Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence

Don't make the nav sticky — this design lets it scroll away to maximize content focus
