zkVerify Design System

1. Brand Identity

Protocol: zkVerify — "Zero Doubt" Purpose: Universal verification layer for zero-knowledge proofs. Style: Light-first (~70%) with strategic dark accents (~30%). Green (Pulse) and blue (Signal) accent colors on clean light surfaces, with Void (deep dark) for hero sections, footer, marquee, and CTAs. Color Ratio: Shell/white surfaces ~70%, Void/dark surfaces ~30%. Primary accent: Pulse (green). Secondary accent: Signal (blue).

3. Typography Overview

• Headings: Monigue — blocky, condensed, uppercase display font. Used for all heading levels.
• Body/UI: Space Grotesk — default weight 300 (Light), NOT 400 Regular. Clean geometric sans-serif.
• Surheadings: 15px, letter-spacing: 4px, uppercase, Space Grotesk. Placed above main headings as category/context labels.

Full type scale (19 styles) in references/tokens.md.

4. Key Design Rules

1. Always use CSS custom properties (--zk-*) for all colors, spacing, typography, shadows, transitions.
2. Primarily light mode (~70%) — Shell/white default. Dark (Void) surfaces ~30% for hero, footer, marquee, CTAs.
3. Buttons are ALWAYS pills — border-radius: 9999px.
4. Headings: Monigue (uppercase). Body: Space Grotesk (weight 300). Never swap them.
5. Cards: 10px border-radius — distinct from Horizen (12px) and Horizen Labs (0px).
6. Body text defaults to Light (300) weight — heavier weights (500, 600, 700) only for emphasis.
7. Surheadings above main headings — 15px uppercase, letter-spacing 4px, provides context for the heading below.
8. Primary accent: Pulse (green). Secondary: Signal (blue). Pulse for CTAs and success; Signal for links and interactive states.
9. Focus rings use Pulse color — outline: 2px solid var(--zk-pulse); outline-offset: 2px.
10. 8px spacing grid — all spacing uses --zk-space-* tokens.
11. All transitions use tokens — --zk-transition-fast, -normal, -slow.

5. Spacing

Base grid: 8px. All spacing derived from --zk-space-* tokens.

Token	Value	Token	Value
--zk-space-1	4px	--zk-space-8	32px
--zk-space-2	8px	--zk-space-10	40px
--zk-space-3	12px	--zk-space-12	48px
--zk-space-4	16px	--zk-space-16	64px
--zk-space-5	20px	--zk-space-20	80px
--zk-space-6	24px	--zk-space-24	96px

Section padding: 64px 40px desktop, 48px 24px tablet, 32px 16px mobile.

6. Border Radius

Token	Value	Usage
--zk-radius-sm	4px	Small elements, tags
--zk-radius-md	8px	Inputs, small cards
--zk-radius-lg	10px	Cards, containers (zkVerify signature)
--zk-radius-xl	16px	Modals, large cards
--zk-radius-2xl	24px	Feature sections
--zk-radius-full	9999px	Buttons, pills, badges

Key rule: Buttons always --zk-radius-full (pill). Cards always --zk-radius-lg (10px).

7. Layout Patterns

Page structure:

• Light surfaces ~70% (Shell --zk-shell, White --zk-white)
• Dark surfaces ~30% (hero, footer, marquee, CTA sections using --zk-void)

Container: max-width: 1440px; margin: 0 auto; padding: 0 40px (16px mobile).

Grid: CSS Grid, 12-column on desktop, responsive collapse.

desktop: repeat(12, 1fr), gap: 24px
tablet:  repeat(6, 1fr),  gap: 16px
mobile:  1fr,             gap: 16px

Section padding (responsive):

desktop: 64px 40px
tablet:  48px 24px
mobile:  32px 16px

8. Responsive Breakpoints

Name	Min-width	Typical use
Mobile	0	Single column, stacked
sm	640px	Small adjustments
md	768px	Tablet, 2-col grid
lg	1024px	Desktop nav, 3-col
xl	1280px	Full desktop layout
2xl	1536px	Large screens

9. Z-Index Scale

Token	Value	Usage
--zk-z-dropdown	100	Dropdowns, popovers
--zk-z-sticky	150	Sticky headers
--zk-z-nav	200	Navigation, bottom bar
--zk-z-overlay	300	Overlays, backdrops
--zk-z-modal	400	Modals, bottom sheets
--zk-z-toast	500	Toasts, snackbars
--zk-z-tooltip	600	Tooltips

10. Transitions & Animation

Token	Value
--zk-transition-fast	150ms ease
--zk-transition-normal	300ms ease
--zk-transition-slow	500ms ease
--zk-transition-spring	500ms cubic-bezier(0.34, 1.56, 0.64, 1)

Key animations:

• fadeIn — opacity 0 to 1, 300ms
• slideUp — translateY(20px) to 0, 300ms
• slideDown — translateY(-20px) to 0, 300ms
• shimmer — background position sweep, 1.5s infinite (skeleton loading)
• pulseGlow — scale 1 to 1.05, 2s infinite (attention, Pulse color glow)
• spin — rotate 360deg, 1s linear infinite (loading)
• marquee — horizontal scroll, linear infinite
• verifyCheck — scale/opacity entrance for verification success badge

11. Accessibility

• Color contrast: WCAG 2.1 AA minimum (4.5:1 text, 3:1 large/UI)
• Focus visible: outline: 2px solid var(--zk-pulse); outline-offset: 2px
• Keyboard navigable: all interactive elements reachable via Tab
• ARIA labels on icon-only buttons
• prefers-reduced-motion: reduce — disable animations, use opacity-only transitions
• Semantic HTML: proper heading hierarchy, landmarks, lists
• Skip navigation link
• Touch targets: 44x44px minimum
