rendu réel · source de vérité

storybook.js.org is built on a pure-white canvas (rgb(255, 255, 255)). The system uses rgb(255, 255, 255) as the singular interactive color. Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside __Nunito_Sans_ee04dc as the primary typeface. A restrained elevation system (3 distinct shadows) — shadows reserved for the few elements that must lift off the page. Motion is a first-class concern — 9 keyframe animations plus transition-driven interactions.

Do's & Don'ts

15 enforceable rules pulled verbatim from the spec

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
