Decoded design system

WorkOS's decoded design system: background #FFFFFF, text #29363D, accent #6363F1, link #6363F1, primary #29363D; type scale h1 80px / h2 52px / body 14px; 4px spacing base; 5px base radius. The single interactive/action color is #6363F1 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #6363F1 — the single interactive color; only on things you click or must notice, never large fills.
• accent, link, button_bg are all #6363F1 — one role, not several (the action color).
• accent #6363F1 — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
• primary #29363D — ≈ the text color — a foreground/text color, not an action color (action = #6363F1).
• secondary #23F0C3 — 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.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F2F2F3` |
| border | `#DEE0E1` |

**Using these colors**

- **Action color** `#6363F1` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `link`, `button_bg` are all `#6363F1` — one role, not several (your action color).
- **accent** `#6363F1` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **primary** `#29363D` — ≈ the text color — a foreground/text color, not an action color (action = #6363F1).
- **secondary** `#23F0C3` — 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): `#FFFFFF` 88.6% · `#EEEFF6` 6.4% · `#A4ABD4` 4.9%

## Typography

- Heading: **Untitled Sans** _(free fallback: Newsreader)_
- Body: **Untitled Sans** _(free fallback: Newsreader)_
- Mono: **IBM Plex Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 80px / 500 · lh 84px · tracking -5.6px |
| h2 | 52px / 500 · lh 56px · tracking -2.6px |

| body | 14px / 400 · lh 17px |
| small | 12px / 400 · lh 18px |
| eyebrow | 12px / 500 · tracking 1.2px |

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

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 8px, 12px, 14px, 16px, 18px, 20px, 22px, 24px, 26px — snap all gaps/padding to these
- section rhythm: 120px top/bottom padding per section (measured)

## Radius
- base: 5px
- button: 100px
- card: 100px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|

**States (measured, not guessed)**

- primary hover: background `#7777F3`
- primary focus: outline `2px solid rgba(99, 99, 241, 0.3)`
- transition: `background-color 0.2s ease`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0.04) 0px 0px 0px 1px, rgba(0, 0, 0, 0.17) 0px 5px 10px -4px`
- card: `rgba(0, 0, 0, 0.08) 0px 8px 24px 0px`

## Motion
- durations: 200ms (dominant) · 150ms
- easings: `ease` (dominant)
- animated properties: border-color, color, left, background-color

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

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- container max 1200px
- nav: 83px relative

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 1118 | 1069 | — | — | 120/120 | — |
| 2187 | 1721 | — | — | 120/0 | — |
| 3908 | 967 | — | — | 120/120 | — |

## Motion choreography (measured)
Load order: `div.code-tabs-active-line` @0ms → `div.cs-cards-container` @4072ms → `div.cs-cards-slide`×54 @4072ms → `div.cs-card-content`×2 @4072ms → `div.cs-nav-container` @4072ms
- `div.cs-cards-slide` ×24 — transform translateX(-22386%) scale(-6)→translateX(-21188.8%) scale(-5.8) — 400ms ease
- scroll reveal: 10 elements rest at opacity 0, translateY(-20px), animate in over 1400ms (5 revealed during the drive).
- overlay dialog (auto-opened): panel #FFFFFF · r 10px · border 1px solid rgba(0, 9, 50, 0.12) · shadow rgba(0, 0, 0, 0.08) 0px 8px 24px 0px

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

## Components (measured)
- link: rgba(6, 0, 171, 0.675) · no underline

## Responsive (measured)
- breakpoints: 479px · 768px · 991px
- mobile (390px): hero 42px · 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.
