Tokens

Sleep Cycle Mobile's decoded design system: background #061620, text #FF7000, accent #174A5F, link #174A5F, primary #174A5F; type scale h1 34px / h2 22px / body 17px; 8px spacing base; 12px base radius. The single interactive/action color is #174A5F — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#061620`
surface	`#141B1E`
border	`#2B231B`
text	`#FF7000`
text_muted	`#A04D0C`

accent	`#174A5F`
link	`#174A5F`
button_bg	`#174A5F`
button_text	`#061620`

Using these colors

Action color #174A5F — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #174A5F — one role, not several (the action color).
accent #174A5F — 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.

# Sleep Cycle Mobile — Design System

> dark, consumer, high — deep decode (measured live)

Sleep Cycle Mobile — palette measured from official store listing screenshots (colors only; no font claims). Type scale shown is the platform HIG default.

## Colors

| Role | Value |
|------|-------|
| bg | `#061620` |
| surface | `#141B1E` |
| border | `#2B231B` |
| text | `#FF7000` |
| text_muted | `#A04D0C` |
| primary | `#174A5F` |
| accent | `#174A5F` |
| link | `#174A5F` |
| button_bg | `#174A5F` |
| button_text | `#061620` |

**Using these colors**

- **Action color** `#174A5F` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent`, `link`, `button_bg` are all `#174A5F` — one role, not several (your action color).
- **accent** `#174A5F` — 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.
- **Page coverage** (full-page screenshot pixels): `#2C3C6B` 26% · `#161F22` 22.2% · `#565980` 14.3% · `#D48976` 13.7%

## Typography


| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 256px / 500 · lh 371px · tracking -10.22px |
| h2 | 84px / 500 · lh 86px · tracking -3.36px |
| h3 | 80px / 400 · lh 80px · tracking -3.2px |
| body | 20px / 400 · lh 26px · tracking -0.4px |
| small | 19px / 500 · lh 28px · tracking -0.4px |
| eyebrow | 16px / 500 · tracking 1.28px |

- Weight ladder: 300 · 400 · 500 · 600 — use these exact measured weights, not the 400/600 defaults.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 3px, 6px, 10px, 12px, 14px, 15px, 16px, 20px, 24px, 32px — snap all gaps/padding to these
- section rhythm: 64px top/bottom padding per section (measured)

## Radius
- base: 12px
- button: 12px
- card: 15px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#161F22` / `#EEEEEE` | 2px solid rgb(22, 31, 34) | 3.75px | 15px 15px 15px 15px | 600 15px / 0.1px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#000000` | none | 3.35544e+07px | 2px 2px 2px 2px | 500 14px / -0.4px | none |

**States (measured, not guessed)**

- primary focus: outline `2px solid rgb(238, 238, 238)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.1) 0px 8px 8px 0px`
- overlay: `rgba(0, 0, 0, 0.3) 0px 30px 70px 0px`

## Motion
- durations: 300ms (dominant) · 150ms · 280ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `linear`
- animated properties: transform, color, opacity, text-decoration-color

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

## Their own tokens (verbatim from :root)

| Token | Value |
|-------|-------|
| `--background` | `#fff` |
| `--foreground` | `#0a0a0a` |
| `--card` | `#fff` |
| `--card-foreground` | `#0a0a0a` |
| `--popover` | `#fff` |
| `--popover-foreground` | `#0a0a0a` |
| `--primary` | `#171717` |
| `--primary-foreground` | `#fafafa` |
| `--secondary` | `#f5f5f5` |
| `--secondary-foreground` | `#171717` |
| `--muted` | `#f5f5f5` |
| `--muted-foreground` | `#737373` |

## Layout (measured)
- container max 1352px · common grid: 2-col
- nav: 80px relative

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 128 | 764 | — | — | 0/0 | — |
| 892 | 231 | 2 | 12 | 56/56 | — |
| 1123 | 1627 | 3 | 8 | 64/64 | — |
| 2750 | 386 | — | — | 64/64 | — |
| 3136 | 1632 | — | — | 64/64 | — |

## Motion choreography (measured)
Load order: `div.animate-ticker`×4 @0ms → `` @0ms → `span.index-module__jvG1Hq__sa`×2 @0ms → `button.index-module__jvG1Hq__gr` @0ms
- `div.animate-ticker` ×2 — transform translate(0%)→translate(calc(-100% - 50px)) — 20000ms · loops
- `span.index-module__jvG1Hq__sa` ×2 — transform none→scale(1) — 1000ms ease · loops
- stagger: `span` ×4 — 55ms apart
- overlay dialog (auto-opened): panel #F2F2F2 · r 0px
  - enter: opacity from 0.5 · 150ms cubic-bezier(0.4, 0, 0.2, 1) | transform from translateX(-26.4208px) translateY(7.54879px) · 300ms cubic-bezier(0, 0, 0.2, 1)

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

## Components (measured)
- link: #000000 · no underline

## Themes (both measured)
- dark counterpart: bg `#2E2E2E` · text `#D6D6D6`
- tokens that flip between modes:
  - `--background`: `#fff` → `#0a0a0a`
  - `--foreground`: `#0a0a0a` → `#fafafa`
  - `--card`: `#fff` → `#171717`
  - `--card-foreground`: `#0a0a0a` → `#fafafa`
  - `--popover`: `#fff` → `#171717`
  - `--popover-foreground`: `#0a0a0a` → `#fafafa`
  - `--primary`: `#171717` → `#e5e5e5`
  - `--primary-foreground`: `#fafafa` → `#171717`

## Responsive (measured)
- breakpoints: 512px · 600px · 768px · 800px · 1000px · 1200px
- mobile (390px): 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.
