Decoded design system

Liveblocks's decoded design system: background #000000, text #FFFFFF, accent #0090FF, link #918D8D, primary #EBF6FF; type scale h1 64px / h2 52px / body 16px; 4px spacing base; 6px base radius. The single interactive/action color is #FFFFFF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #FFFFFF — the single interactive color; only on things you click or must notice, never large fills.
• accent #0090FF — accent for emphasis — keep it rare on the page.
• primary #EBF6FF — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #FFFFFF).
• link #918D8D — reads as a neutral UI color, not a link accent — verify against the reference (action = #FFFFFF).
• secondary #34A7FF — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.

# Liveblocks — Design System

> dark, modern, medium, tailwind — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#000000` |
| surface | `#0F0F0F` |
| border | `#262626` |
| text | `#FFFFFF` |
| text_muted | `#9E9E9E` |
| primary | `#EBF6FF` |
| accent | `#0090FF` |
| link | `#918D8D` |
| secondary | `#34A7FF` |
| button_bg | `#FFFFFF` |
| button_text | `#000000` |

**Using these colors**

- **Action color** `#FFFFFF` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- **accent** `#0090FF` — accent for emphasis — keep it rare on the page.
- **primary** `#EBF6FF` — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #FFFFFF).
- **link** `#918D8D` — reads as a neutral UI color, not a link accent — verify against the reference (action = #FFFFFF).
- **secondary** `#34A7FF` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#000000` 82.1% · `#100F10` 5.5% · `#CDB1C1` 3.5% · `#41232E` 2.5%

## Typography

- Heading: **Suisse Intl** _(free fallback: Newsreader)_
- Body: **Suisse Intl** _(free fallback: Newsreader)_
- Mono: **JetBrains Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 64px / 500 · lh 70px · tracking -1.28px |
| h2 | 52px / 500 · lh 57px · tracking -1.04px |
| h3 | 48px / 500 · lh 50px |
| body | 16px / 500 · lh 22px · tracking 0.06px |
| small | 14px / 500 · lh 20px |
| eyebrow | 14px / 400 · tracking 0.35px |

- Weight ladder: 400 · 500 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Suisse Intl may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 5px, 6px, 8px, 9px, 12px, 14px, 16px, 20px — snap all gaps/padding to these
- section rhythm: 196px top/bottom padding per section (measured)

## Radius
- base: 6px
- button: 6px
- card: 6px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFFFFF` / `#000000` | none | 6px | 0px 14px 0px 14px | 500 14px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#FFFFFF` | none | 8px | 0px 16px 0px 16px | 500 16px | none |

**States (measured, not guessed)**

- primary hover: background `#B7B4B4`
- transition: `color 0.3s cubic-bezier(0, 0, 0.2, 1)`

## Motion
- durations: 100ms (dominant) · 150ms · 300ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `cubic-bezier(0, 0, 0.2, 1)`
- animated properties: opacity, none, color, box-shadow

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

## Layout (measured)
- container max 768px · common grid: 12-col
- nav: 80px fixed

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 80 | 1272 | — | — | 0/40 | — |
| 1384 | 193 | — | — | 0/0 | — |
| 1857 | 664 | — | — | 0/0 | — |

## Motion choreography (measured)
Load order: `div.-ml-1.5` @0ms → `img.pointer-events-none` @843ms → `img.size-full`×3 @844ms → `div.absolute`×2 @844ms → `div.z-20`×2 @844ms → `span.transition`×2 @4853ms
- `img.size-full` — opacity 0→1 — 500ms cubic-bezier(0.4, 0, 0.2, 1)
- stagger: `span` ×4 — 100ms apart
- scroll reveal: 2 elements rest at opacity 0, animate in over 0.15s cubic-bezier(0, 0, 0.2, 1) (0 revealed during the drive).

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)
- link: #918D8D · underline — hover #FFFFFF

## Responsive (measured)
- breakpoints: 640px · 768px · 1024px · 1280px · 1536px
- mobile (390px): hero 36px · body 16px · nav: hamburger

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
