Tokens

Messenger Mobile's decoded design system: background #FFFFFF, text #000000, accent #26877F, link #26877F, primary #26877F; type scale h1 34px / h2 22px / body 17px; 8px spacing base; 12px base radius. The single interactive/action color is #26877F — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Messenger Mobile — Design System

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

Messenger 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 | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#26877F` |
| accent | `#26877F` |
| link | `#26877F` |
| button_bg | `#26877F` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#26877F` — 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 `#26877F` — one role, not several (your action color).
- **accent** `#26877F` — 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): `#999999` 61.1% · `#FFFFFF` 27% · `#737F91` 7.6% · `#D1D3D4` 4.4%

## Typography


| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 80px / 600 · lh 85px · tracking -3.2px |
| h2 | 21px / 600 · lh 18px |
| h3 | 19px / 500 · lh 18px |
| body | 15px / 400 · lh 18px |
| small | 14px / 600 · lh 18px |

- Weight ladder: 400 · 500 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 2px, 5px, 6px, 8px, 10px, 16px, 20px, 25px, 30px, 40px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 12px
- card: 12px
- sharp: 3px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#0866FF` / `#FFFFFF` | 1px solid rgb(0, 112, 246) | 24px | 2px 20px 0px 20px | 600 19px | none |

**States (measured, not guessed)**

- primary hover: border `1px solid rgb(0, 58, 185)` · background `#003AB9`
- primary focus: box-shadow `rgb(255, 255, 255) 0px 0px 0px 2px, rgb(24, 119, 242) 0px 0px 0px 4px`
- transition: `background-color 0.2s cubic-bezier(0.08, 0.52, 0.52, 1)`

## Shadows (elevation)
- subtle: `rgba(88, 144, 255, 0.75) 0px 0px 1px 2px, rgba(0, 0, 0, 0.15) 0px 1px 1px 0px`
- card: `rgba(0, 0, 0, 0.3) 0px 2px 26px 0px, rgba(0, 0, 0, 0.1) 0px 0px 0px 1px`

## Motion
- durations: 200ms (dominant)
- easings: `cubic-bezier(0.08, 0.52, 0.52, 1)` (dominant) · `ease-in`
- animated properties: opacity, background-color, box-shadow, transform

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 |
|-------|-------|
| `--xbot0hz` | `#171C1F` |
| `--x1dxtr3h` | `#191C1F` |
| `--x1fo8oi` | `rgba(230, 230, 230, .8)` |
| `--x3ssoic` | `#E6E6E6` |
| `--x1fvvt15` | `#CED0D4` |
| `--xcx8qie` | `rgba(161, 187, 255, .16)` |
| `--x1i50v3k` | `#EBEDF0` |
| `--xdbh3ft` | `rgba(0, 100, 224, .25)` |
| `--x1bd2fwr` | `#ECF5FF` |
| `--x11rivb9` | `#f3f4f5` |
| `--x5afhcp` | `#f9fafb` |
| `--xhj0bg5` | `#f9fafb` |

_…and 108 more measured on the page._

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

## Layout (measured)
- nav: 100px absolute

## Motion choreography (measured)
Load order: `a._42ft` @0ms
- overlay dialog (auto-opened): panel #FFFFFF · r 3px · shadow rgba(0, 0, 0, 0.3) 0px 2px 26px 0px, rgba(0, 0, 0, 0.1) 0px 0px 0px 1px

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

## Components (measured)
- input: h 36px · r 10px · bg rgba(0, 0, 0, 0.04) · placeholder #65686C
- link: #0A7CFF · no underline

## Responsive (measured)
- breakpoints: 679px · 768px · 1024px · 1440px · 1920px
- mobile (390px): hero 25px · body 12px · 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.
