Tokens

X Mobile's decoded design system: background #000000, text #BFBFBF, accent #1572B1, link #1572B1, primary #1572B1; type scale h1 34px / h2 22px / body 17px; 4px spacing base; 12px base radius. The single interactive/action color is #1572B1 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#000000`
surface	`#0B0B0B`
border	`#1C1C1C`

Using these colors

Action color #1572B1 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #1572B1 — one role, not several (the action color).
accent #1572B1 — 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.

# X Mobile — Design System

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

X 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 | `#000000` |
| surface | `#0B0B0B` |
| border | `#1C1C1C` |
| text | `#BFBFBF` |
| text_muted | `#767676` |
| primary | `#1572B1` |
| accent | `#1572B1` |
| link | `#1572B1` |
| button_bg | `#1572B1` |
| button_text | `#000000` |

**Using these colors**

- **Action color** `#1572B1` — 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 `#1572B1` — one role, not several (your action color).
- **accent** `#1572B1` — 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): `#FFFFFF` 73% · `#0F1419` 18.2% · `#E9EBEB` 6.2% · `#525455` 2.6%

## Typography


| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 64px / 600 · lh 58px · tracking -1px |
| h2 | 17px / 500 · lh 20px |
| body | 13px / 400 · lh 16px |
| small | 12px / 500 · lh 18px |

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 12px, 16px, 20px, 24px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 12px
- card: 20px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#EFF3F4` / `#000000` | 1px solid rgba(0, 0, 0, 0) | 9999px | 0px 16px 0px 16px | 400 15px | none |
| secondary | `#EFF3F4` / `#000000` | 1px solid rgba(0, 0, 0, 0) | 9999px | 0px 16px 0px 16px | 400 15px | none |

**States (measured, not guessed)**

- primary hover: background `#D7DBDC`
- primary focus: box-shadow `rgb(247, 249, 250) 0px 0px 0px 2px` · background `#D7DBDC`
- secondary hover: background `#D7DBDC`
- transition: `background-color 0.2s ease`

## Shadows (elevation)
- card: `rgba(101, 119, 134, 0.2) 0px 0px 7px 0px, rgba(101, 119, 134, 0.15) 0px 1px 3px 1px`

## Motion
- durations: 150ms (dominant) · 200ms · 218ms
- easings: `ease` (dominant) · `ease-out`
- animated properties: background-color, transform, box-shadow, 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.

## Layout (measured)
- container max 1280px · common grid: 2-col
- nav: 52px relative

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 0 | 900 | 2 | — | 0/0 | 42/58 |

## Motion choreography (measured)
Load order: `div.css-175oi2r` @0ms → `div.css-175oi2r` @359ms → `div.jf-element` @426ms → `div.jf-element` @426ms → `span.jf-element` @673ms → `span.jf-element` @673ms

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 `#000000` · text `#FFFFFF`

## Responsive (measured)
- breakpoints: 768px
- mobile (390px): hero 20px · body 15px · 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.
