real render · source of truth

vitejs.dev is built on a near-black canvas (rgb(22, 23, 29)). The system uses rgb(255, 255, 255) as the singular interactive color. Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside APK Protocol as the primary typeface. APK Protocol is paired with KH Teka Mono for secondary roles. A restrained elevation system (2 distinct shadows) — shadows reserved for the few elements that must lift off the page. Motion is a first-class concern — 8 keyframe animations plus transition-driven interactions.

Do's & Don'ts

23 enforceable rules pulled verbatim from the spec

Use dark background (`#16171d`) as the foundation — this is a dark-mode-native design

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

Keep font weights between 400-600 — the system uses a narrow weight range for subtle hierarchy

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 White (`#ffffff`) 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

Apply 40px 32px padding inside cards — matches the design system's content breathing room

Use 8px border-radius on cards — consistent with the grid card corners

Maintain nav height at 40px — consistent vertical space for the navigation bar

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

Show person avatars with testimonials — social proof is human-centric here

Lay out testimonials in a grid (9+ items) — quantity signals scale and trust

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 use weight 700 (bold) or above — 600 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 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
