Tokens

Grok Mobile's decoded design system: background #0A0A0A, text #FFFFFF, accent #7C1D12, link #7C1D12, primary #7C1D12; type scale h1 34px / h2 22px / body 17px; 4px spacing base; 12px base radius. The single interactive/action color is #7C1D12 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #7C1D12 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, link, button_bg are all #7C1D12 — one role, not several (the action color).
• accent #7C1D12 — 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.

# Grok Mobile — Design System

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

Grok 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 | `#0A0A0A` |
| surface | `#181818` |
| border | `#2E2E2E` |
| text | `#FFFFFF` |
| text_muted | `#A1A1A1` |
| primary | `#7C1D12` |
| accent | `#7C1D12` |
| link | `#7C1D12` |
| button_bg | `#7C1D12` |
| button_text | `#0A0A0A` |

**Using these colors**

- **Action color** `#7C1D12` — 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 `#7C1D12` — one role, not several (your action color).
- **accent** `#7C1D12` — 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): `#FCFCFC` 90.7% · `#000000` 8.1% · `#959595` 1.2%

## Typography

- h1: 34px
- h2: 22px
- body: 17px

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 10px, 12px, 14px, 16px, 24px, 30px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 12px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#000000` / `#EEEEEE` | 1px solid rgb(238, 238, 238) | 9999px | 12px 10px 12px 10px | 600 13.008px / 0.13008px | none |
| secondary | `oklch(0.1157 0 none)` / `#FCFCFC` | none | 9999px | 8px 16px 8px 16px | 500 14px / -0.1px | none |

**States (measured, not guessed)**

- primary focus: outline `1px solid rgb(138, 138, 138)`
- secondary hover: background `oklch(0.2801 0 none)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.2) 0px 0px 18px 0px`

## Motion
- durations: 100ms (dominant) · 150ms · 300ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease-in-out`
- animated properties: background-color, border-color, color, 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 |
|-------|-------|
| `--input-button-background-hover` | `oklch(96.12% 0 none)` |
| `--input-border` | `oklch(90.01% 0 none/.38)` |
| `--toggle-hover` | `oklch(99.24% 0 none)` |
| `--card-border` | `oklch(95.5% .0092 274.92)` |
| `--card` | `oklch(99.24% 0 none/.8)` |
| `--thead-border-b-color` | `oklch(11.57% 0 none/.1)` |
| `--bg-warning` | `hsl(47 100% 45% / .08)` |
| `--important-hover` | `oklch(98.48% 0 none)` |
| `--link-hover` | `oklch(72.44% .1266 271.21)` |
| `--incognito-input-background` | `oklch(95.78% .0057 308.39)` |
| `--highlight` | `oklch(89.28% .0457 270.86/.4)` |
| `--input-button-border-hover` | `oklch(91.58% 0 none)` |

_…and 80 more measured on the page._

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

## Layout (measured)
- container max 800px

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 0 | 900 | — | — | 16/16 | — |

## Motion choreography (measured)
Load order: `div.max-w-breakout` @0ms → `div.otFloatingRounded` @13ms → `` @285ms
- overlay dialog (auto-opened): panel rgba(0, 0, 0, 0) · r 0px
  - exit: transform+opacity from none,1 · 150ms linear

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

## Components (measured)
- input: h 60px · r 0px · bg rgba(0, 0, 0, 0) · placeholder #636363
  - focus ring: `2px solid rgba(0, 0, 0, 0)` — this exact construction, don't invent your own
- link: #050505 · no underline
- disabled: bg rgba(0, 0, 0, 0) · text #050505

## Themes (both measured)
- dark counterpart: bg `#050505` · text `#FCFCFC`
- tokens that flip between modes:
  - `--input-button-background-hover`: `oklch(96.12% 0 none)` → `oklch(38.55% .0043 247.94)`
  - `--input-border`: `oklch(90.01% 0 none/.38)` → `oklch(90.01% 0 none/.04)`
  - `--toggle-hover`: `oklch(99.24% 0 none)` → `oklch(99.24% 0 none/.06)`
  - `--card-border`: `oklch(95.5% .0092 274.92)` → `oklch(90.01% 0 none/.04)`
  - `--card`: `oklch(99.24% 0 none/.8)` → `oklch(90.01% 0 none/.08)`
  - `--bg-warning`: `hsl(47 100% 45% / .08)` → `hsl(48 98% 62% / .1)`
  - `--important-hover`: `oklch(98.48% 0 none)` → `oklch(33.11% 0 none)`
  - `--link-hover`: `oklch(72.44% .1266 271.21)` → `oklch(50.04% .1778 267.72)`

## Responsive (measured)
- breakpoints: 426px · 550px · 600px · 640px · 768px · 896px
- 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.
