description

Design system for the Horizen Labs company website (www.horizenlabs.io). Use this skill whenever building UI, components, pages, or layouts for Horizen Labs — including when the user mentions Horizen Labs, hl- tokens, horizenlabs.io, or needs to create institutional/technical UI following Horizen Labs' navy/teal/magenta brand with sharp corners. Also use when the user references horizenlabs-design-system.html or asks about Horizen Labs design tokens, typography (Azeret Mono, Roboto), component patterns, or the sharp-corner design philosophy.

Horizen Labs Design System

1. Brand Identity

Company: Horizen Labs — developer company building blockchain infrastructure (NOT the Horizen protocol). Tagline: "Building the Infrastructure of the Verifiable Web" Style: Sharp, institutional, monospace-driven. Navy/teal dominance, no rounded corners. Surfaces: Almost entirely light mode (~100%) — white/grey-light default. Dark (navy) ONLY for nav CTA, modal overlays, drawers, rare dark cards. Target: www.horizenlabs.io Source: Figma "HL WEB 2.0" (4vyFlIPGnd66tBXk764WXA) Visual Reference: horizenlabs-design-system.html — all 33 sections rendered

2. Quick Color Reference

Token	Hex	Usage
--hl-navy	#041742	Primary brand, text, dark accents
--hl-teal	#4CDFDD	Accent, borders, highlights
--hl-teal-text	#00C0BD	Teal text for links and emphasis
--hl-white	#FFFFFF	Page backgrounds
--hl-grey	#BABDC3	Secondary text, borders
--hl-grey-light	#F5F6F8	Alt section backgrounds, inputs
--hl-magenta	#F251EA	Accent, highlights, special CTAs

3. Typography Overview

• Headings: Azeret Mono, 700 Bold (monospace, technical feel)
• Body/UI: Roboto, 400/500/600/700 weights
• CTAs, nav links, badges, labels: ALWAYS uppercase with wide letter-spacing (2.4-3.8px)

Full type scale in references/tokens.md.

4. Key Design Rules

1. Always use CSS custom properties (--hl-*) for all colors, spacing, typography, shadows, transitions.
2. Almost entirely light mode (~100%) — white/grey-light default. Dark (navy) ONLY for nav CTA, modal overlays, drawers, rare dark cards.
3. EVERYTHING sharp-cornered — border-radius: 0 on buttons, cards, inputs, badges, modals, avatars. This is THE core brand distinction.
4. CTAs, nav links, badges, labels are ALWAYS uppercase with letter-spacing (2.4-3.8px).
5. Headings: Azeret Mono. Body: Roboto. Never swap them.
6. Footer uses teal background (not dark like other brands).
7. Cards hover with three-part effect — lift (translateY) + shadow escalation + gradient border reveal. See references/polish.md.
8. Alerts use left-border style — 4px solid left border, status color bg at 12%.
9. Link buttons use square arrow-box icons — 25x25px, 2px border, 45-degree chevron.
10. Nav CTA is an integrated navy block — not a standard button.
11. Gradient accent bar at top of every page — 3px magenta→teal, fixed position. Footer mirrors it.
12. Frosted glass navbar — rgba(255,255,255,0.85) + backdrop-filter: blur(20px), sits below accent bar.
13. Button/card hover always lifts — translateY(-2px) buttons, -4px to -6px cards, with shadow escalation.
14. Background patterns on hero/feature sections — grid lines or dot patterns, always with radial mask fade.
15. Ambient glow blobs on hero sections — large blurred teal/magenta circles, max 2 per section.

5. Spacing

Custom scale (not strict 8px grid). All spacing uses --hl-space-* tokens.

Token	Value	Token	Value
--hl-space-1	4px	--hl-space-10	40px
--hl-space-2	8px	--hl-space-12	50px
--hl-space-3	10px	--hl-space-14	60px
--hl-space-4	12px	--hl-space-16	80px
--hl-space-5	16px	--hl-space-20	100px
--hl-space-6	20px	--hl-space-24	120px
--hl-space-8	25px	--hl-space-28	150px
		--hl-space-32	200px

Section padding: 150px 100px large desktop, 80px 40px tablet, 40px 20px mobile.

6. Border Radius

Token	Value	Usage
--hl-radius-none	0px	DEFAULT for everything
--hl-radius-sm	2px	Rare, subtle rounding
--hl-radius-md	4px	Occasional, minor elements

KEY RULE: Everything defaults to 0. Sharp corners are the core brand identity. Never use border-radius: 9999px or large radii.

7. Layout Patterns

Page structure:

• Light surfaces ~100% (white --hl-white, grey-light --hl-grey-light)
• Teal footer background
• Dark (navy) only for nav CTA, overlays, rare accent cards
• Gradient CTAs are rare and reserved for special emphasis

Container: max-width: 1440px; margin: 0 auto; padding: 0 100px (20px mobile).

Grid: CSS Grid, responsive collapse.

desktop: repeat(12, 1fr), gap: 30px
tablet:  repeat(6, 1fr),  gap: 20px
mobile:  1fr,             gap: 16px

Section padding (responsive):

large desktop: 150px 100px
desktop:       100px 60px
tablet:         80px 40px
mobile:         40px 20px

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
--hl-z-dropdown	100	Dropdowns, popovers
--hl-z-sticky	150	Sticky headers
--hl-z-nav	200	Navigation
--hl-z-overlay	300	Overlays, backdrops
--hl-z-modal	400	Modals, drawers
--hl-z-toast	500	Toasts, notifications
--hl-z-tooltip	600	Tooltips

10. Transitions & Animation

Token	Value
--hl-transition-fast	150ms ease
--hl-transition-normal	all 0.3s ease
--hl-transition-slow	500ms ease
--hl-transition-border	0.4s ease

Key animations:

• fadeIn — opacity 0 to 1, 300ms
• slideUp — translateY(20px) to 0, 300ms
• slideDown — translateY(-20px) to 0, 300ms
• log-blink — teal bg pulse, 0.6s, 3 repetitions
• pulse-text — opacity 1→0.4→1, 2s infinite (processing labels)

V2 Polish interactions (see references/polish.md):

• Button hover: translateY(-2px) + shadow lift
• Card hover: translateY(-4px to -6px) + shadow escalation + gradient border reveal
• Border reveals: 0.4s ease (staggered behind the faster card lift)

11. Accessibility

• Color contrast: WCAG 2.1 AA minimum (4.5:1 text, 3:1 large/UI)
• Focus visible: outline: 2px solid var(--hl-teal); 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
