Decoded design system

Grok Mobile's decoded design system: background #FCFCFC, text #050505, 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 #050505 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FCFCFC`
surface	`#EDEDED`
border	`#D6D6D6`
text	`#050505`
text_muted	`#626262`
primary	`#7C1D12`
accent	`#7C1D12`
link	`#7C1D12`
button_bg	`#050505`
button_text	`#EEEEEE`

Using these colors

Action color #050505 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link are all #7C1D12 — one role, not several (the action color).
accent #7C1D12 — accent for emphasis — keep it rare on the page.

# Grok Mobile — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FCFCFC` |
| surface | `#EDEDED` |
| border | `#D6D6D6` |
| text | `#050505` |
| text_muted | `#626262` |
| primary | `#7C1D12` |
| accent | `#7C1D12` |
| link | `#7C1D12` |
| button_bg | `#050505` |
| button_text | `#EEEEEE` |

**Using these colors**

- **Action color** `#050505` — 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` are all `#7C1D12` — one role, not several.
- **accent** `#7C1D12` — accent for emphasis — keep it rare on the page.
- **Page coverage** (full-page screenshot pixels): `#FCFCFC` 98.4% · `#8E8E8E` 1.6%

## Typography

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 12px, 14px, 16px, 24px, 44px, 48px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#050505` / `oklch(0.9772 0 none)` | none | 9999px | 4px 12px 4px 12px | 500 14px / -0.1px | 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 `2px solid rgb(56, 87, 199)`
- secondary hover: background `oklch(0.2801 0 none)`
- transition: `color 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 0px 30px -5px, rgba(0, 0, 0, 0.1) 0px 0px 6px -4px`
- card: `rgb(255, 255, 255) 0px 0px 0px 0px, rgba(5, 5, 5, 0.15) 0px 0px 0px 1px, rgba(0, 0, 0, 0) 0px 0px 0px 0px`

## Motion
- durations: 100ms (dominant) · 150ms
- 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)

_…and 98 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.otFloatingRounded` @0ms
- overlay dialog (auto-opened): panel oklch(0.9772 0 none) · r 16px · border 1px solid oklch(0.1157 0 none / 0.06) · shadow rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 0px 30px -5px, rgba(0, 0, 0, 0.1) 0px 0px 6px -4px
  - 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
- 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)`
  - `--cookie-consent-on-primary`: `oklch(97.72% 0 none)` → `oklch(17.8% .0048 274.69)`

## Responsive (measured)
- breakpoints: 426px · 550px · 600px · 640px · 768px · 896px
- mobile (390px): 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.

Is this spec still current?

Grok Mobile is re-measured from its live DOM every night — 16 measurements on record so far. The dated verdict (held, changed, or never settles) is on its drift ledger.
