rendu réel · source de vérité

stripe.com is built on a pure-white canvas (rgb(255, 255, 255)). The system uses rgb(83, 58, 253) as the high-saturation accent for primary actions. Crisp CTAs (4px radius) reinforce a precise, technical aesthetic alongside sohne-var as the primary typeface. A layered elevation system (10 distinct shadows) building a clear front-to-back hierarchy. Interactions are smoothed by transitions across many elements, with little or no keyframe animation.

Do's & Don'ts

21 enforceable rules pulled verbatim from the spec

Do
Use sohne-var as the primary typeface — it defines the brand personality
Keep font weights between 300-400 — the system uses a narrow weight range for subtle hierarchy
Use negative letter-spacing (-0.8px) at display sizes for compressed, editorial headlines
Use the extracted shadow patterns for elevation — they are tuned to match the brand palette
Use Accent (`#533afd`) as the primary accent — it's the brand's signature interactive color
Use small 4px radius for buttons — this design system uses subtle rounding, not pill shapes
Maintain nav height at 64px — consistent vertical space for the navigation bar
Each card includes a top image — imagery is part of the card identity, not optional
Place 2 pricing tiers side-by-side on desktop — direct comparison is the value prop
Lay out testimonials in a grid (18+ items) — quantity signals scale and trust
Use expandable accordion for the FAQ — saves vertical space and lets users self-navigate
Repeat the primary CTA across 5 banner sections — conversion paths are layered, not single
Build a content-dense footer (4 columns, ~80 links) — this site treats the footer as a sitemap, not an afterthought
Don't
Don't substitute with generic sans-serif or serif — the custom font carries the brand
Don't use weight 700 (bold) or above — 400 is the maximum weight in this system
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 introduce additional saturated accent colors — the palette is intentionally controlled
Don't over-round buttons with pill or large radius — the system uses restrained, sharp-ish corners
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
