Tokens

Datadog's decoded design system: background #FFFFFF, text #000000, accent #FFFFFF, link #110617, primary #632CA6; type scale h1 68px / h2 36px / body 28px; 4px spacing base; 4px 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.

# Datadog — Design System

> light, professional, medium, tailwind

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#632CA6` |
| accent | `#FFFFFF` |
| link | `#110617` |
| secondary | `#7700FF` |
| button_bg | `#FFFFFF` |
| button_text | `#555555` |

**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`, `button_bg` are all `#FFFFFF` — one role, not several (your action color).
- **accent** `#FFFFFF` — 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** `#632CA6` — a brand color — but the call-to-action uses #FFFFFF, not this.
- **link** `#110617` — inline text links and link-styled controls.
- **secondary** `#7700FF` — 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.

## Typography

- Heading: **NationalWeb** _(free fallback: Newsreader)_
- Body: **NationalWeb** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 68px / 600 · lh 68px |
| h2 | 36px / 700 · lh 40px |
| h3 | 32px / 300 · lh 38px |
| body | 18px / 700 · lh 18px |
| small | 17px / 300 · lh 22px |
| eyebrow | 18px / 600 · tracking 0.4px |

- Weight ladder: 300 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

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

## Spacing
- base unit: 4px
- scale: 2px, 4px, 6px, 8px, 12px, 16px, 24px, 32px

## Radius
- base: 4px
- button: 4px
- card: 4px
- sharp: 3px

## Primary button
- bg `#FFFFFF` · text `#555555` · radius 4px

## 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.
