rendu réel · source de vérité

astro.build is built on a near-black canvas (rgb(12, 15, 25)). The system uses rgb(97, 218, 251) as the high-saturation accent for primary actions. Fully-rounded CTAs (9999px) signal a friendly, tactile interaction model alongside Obviously as the primary typeface. A layered elevation system (4 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

25 enforceable rules pulled verbatim from the spec

Use dark background (`#0c0f19`) as the foundation — this is a dark-mode-native design

Use ui-sans-serif as the primary typeface — it defines the brand personality

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 #61dafb (`#61dafb`) 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

Use 16px border-radius on cards — consistent with the grid card corners

Style form inputs with a `1px solid rgb(35, 38, 45)` border — use border-based inputs, not floating labels or underline-only

Maintain nav height at 80px — 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 2 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose

Each card includes a top image — imagery is part of the card identity, not optional

Use a 4-column grid on desktop — density matters for this content type

Use expandable accordion for the FAQ — saves vertical space and lets users self-navigate

Include a newsletter signup in the footer — email capture is part of the conversion funnel

Don't

Don't use light backgrounds — the dark canvas is the native medium

Don't substitute with generic sans-serif or serif — the custom font carries the brand

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 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

Don't put a CTA button in the nav — this design uses links only at the top
