Tokens

Exa's decoded design system: background #FFFFFF, text #000000, accent #000000, link #374151, primary #1F40ED; type scale h1 63.2px / h2 48px / body 18.4px; 4px spacing base; 4px base radius. The single interactive/action color is #000000 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Exa — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#1F40ED` |
| accent | `#000000` |
| link | `#374151` |
| secondary | `#EEF8FF` |
| button_bg | `#000000` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#000000` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `button_bg` are all `#000000` — one role, not several (your action color).
- **accent** `#000000` — 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** `#1F40ED` — a brand color — but the call-to-action uses #000000, not this.
- **link** `#374151` — inline text links and link-styled controls.
- **secondary** `#EEF8FF` — 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` 85.9% · `#B2D1D6` 5.6% · `#6789A4` 5% · `#DCE1E1` 3.5%

## Typography

- Heading: **Georgia**
- Body: **Inter**
- Mono: **Geist Mono**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 63px / 400 · lh 46px · tracking -1.9px |
| h2 | 54px / 400 · lh 54px · tracking -1.09px |
| h3 | 48px / 400 · lh 53px · tracking -1.44px |
| body | 15px / 400 · lh 21px · tracking -0.3px |
| small | 14px / 500 · lh 20px · tracking -0.28px |
| eyebrow | 13px / 400 · tracking 0.8px |

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

> **Fonts —** Georgia — system font, no web load needed. Inter — free, on Google.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 3px, 4px, 6px, 7px, 8px, 12px, 16px, 20px, 24px — snap all gaps/padding to these
- section rhythm: 112px top/bottom padding per section (measured)

## Radius
- base: 4px
- button: 4px
- card: 4px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#F2F0EF` / `#514837` | none | 4px | 6px 12px 6px 12px | 500 14px | none |
| secondary | `#000000` / `#FFFFFF` | none | 4px | 6px 12px 6px 12px | 500 14px | none |

**States (measured, not guessed)**

- primary hover: background `#E8E6E5`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: background `#1F2937`
- transition: `color 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.08) 0px 1px 2px 0px, rgba(0, 0, 0, 0.06) 0px 4px 12px 0px`
- card: `rgba(0, 0, 0, 0.1) 0px 10px 15px -3px, rgba(0, 0, 0, 0.1) 0px 4px 6px -4px`

## Motion
- durations: 300ms (dominant) · 150ms · 1400ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease-out`
- animated properties: opacity, color, background-color, border-color

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

_…and 103 more measured on the page._

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

## Layout (measured)
- container max 1280px · common grid: 2-col
- nav: 0px relative · bg #FFFFFF

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 3191 | 822 | 2 | — | 0/0 | 33/67 |
| 4013 | 1160 | 2 | 32 | 112/112 | 84/16 |

## Motion choreography (measured)
Load order: `svg.lucide` @0ms → `span.exa-agent-shimmer-icon-m` @58ms → `div.min-h-0` @58ms → `div.flex` @58ms → `span.absolute`×60 @58ms → ``×4 @58ms
- `div.absolute` ×15 — opacity 0→1 · transform scale(0.85)→scale(1) — 500ms ease-out
- `div.min-h-0` — opacity 0→1 — 200ms ease-out
- `div.flex` — opacity 0→1 — 200ms ease-out
- `span.block` ×3 — opacity 0→1 — 300ms cubic-bezier(0.4, 0, 0.2, 1)
- `span.text-gray-900` ×2 — opacity 0→1 · transform translateY(4px)→translateY(0px) — 600ms ease-out
- `div.flex-1` — opacity 0→1 · transform translateY(8px)→translateY(0px) — 350ms ease
- stagger: `div` ×24 — 60ms apart
- scroll reveal: 3 elements rest at translateY(48px), animate in over 200ms (1 revealed during the drive).

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

## Responsive (measured)
- breakpoints: 640px · 768px · 1024px · 1280px
- mobile (390px): hero 38px · body 16px · nav: inline

## 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.
