Eight Sleep sells sleep as performance hardware: PP Neue Montreal at up to 115px/400 ('Temperature') in white over black product film, 22px body, and a colorless palette that lets thermal gradients and biometric charts provide the glow. It's the Apple-adjacent playbook executed on a mattress — health metrics shot like a car commercial.

Tokens

Eight Sleep's decoded design system: background #FFFFFF, text #000000, accent #E8EFFF, link #4158EE, primary #1862FF; type scale h1 115px / h2 56px / body 22px; 4px spacing base; 8px base radius. The single interactive/action color is #E8EFFF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#EFEFEF`
border	`#D8D8D8`
text	`#000000`
text_muted	`#606060`
primary	`#1862FF`
accent	`#E8EFFF`
link	`#4158EE`
button_bg	`#E8EFFF`
button_text	`#000000`

Using these colors

Action color #E8EFFF — the single interactive color; only on things you click or must notice, never large fills.
accent, button_bg are all #E8EFFF — one role, not several (the action color).
accent #E8EFFF — 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 #1862FF — a brand color — but the call-to-action uses #E8EFFF, not this.
link #4158EE — inline text links and link-styled controls.

# Eight Sleep — Design System

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

Eight Sleep sells sleep as performance hardware: PP Neue Montreal at up to 115px/400 ('Temperature') in white over black product film, 22px body, and a colorless palette that lets thermal gradients and biometric charts provide the glow. It's the Apple-adjacent playbook executed on a mattress — health metrics shot like a car commercial.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#1862FF` |
| accent | `#E8EFFF` |
| link | `#4158EE` |
| button_bg | `#E8EFFF` |
| button_text | `#000000` |

**Using these colors**

- **Action color** `#E8EFFF` — 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 `#E8EFFF` — one role, not several (your action color).
- **accent** `#E8EFFF` — 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** `#1862FF` — a brand color — but the call-to-action uses #E8EFFF, not this.
- **link** `#4158EE` — inline text links and link-styled controls.
- **Page coverage** (full-page screenshot pixels): `#000000` 53% · `#FFFFFF` 27.2% · `#292626` 10.4% · `#F4F1F0` 2.7%

## Typography

- Heading: **PP Neue Montreal** _(free fallback: Space Grotesk)_
- Body: **PP Neue Montreal** _(free fallback: Space Grotesk)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 115px / 400 · lh 115px · tracking 0.45px |
| h2 | 72px / 400 · lh 74px · tracking 0.72px |
| h3 | 64px / 400 · lh 77px · tracking -1.31px |
| body | 18px / 400 · lh 25px · tracking 0.16px |
| small | 16px / 500 · lh 24px |
| eyebrow | 10px / 500 · tracking 0.5px |

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

> **Fonts —** PP Neue Montreal is proprietary — closest free match: Space Grotesk (Google). Load Space Grotesk; keep PP Neue Montreal first so licensed users still get it.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 8px, 10px, 12px, 15px, 16px, 20px, 24px, 32px, 45px — snap all gaps/padding to these
- section rhythm: 112px top/bottom padding per section (measured)

## Radius
- base: 8px
- button: 4px
- card: 50px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(0, 0, 0, 0)` / `#FFFFFF` | none | 8px | 12px 24px 12px 24px | 400 17px | none |
| secondary | `#FFFFFF` / `#FFFFFF` | none | 8px | — | — | none |

**States (measured, not guessed)**

- transition: `all 0.2s ease-out`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.15) 0px 4px 20px 0px`
- overlay: `rgba(0, 0, 0, 0.55) 2.836px 2.836px 90.745px 0px`

## Motion
- durations: 100ms (dominant) · 200ms · 300ms
- easings: `ease` (dominant) · `ease-out`
- animated properties: stroke, background-color, 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.

## 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.
