Tokens

IMDb Mobile's decoded design system: background #121212, text #FFFFFF, accent #F1DD2F, link #F1DD2F, primary #F1DD2F; type scale h1 34px / h2 22px / body 17px; 4px spacing base; 12px base radius. The single interactive/action color is #F1DD2F — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# IMDb Mobile — Design System

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

IMDb 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 | `#121212` |
| surface | `#202020` |
| border | `#353535` |
| text | `#FFFFFF` |
| text_muted | `#A4A4A4` |
| primary | `#F1DD2F` |
| accent | `#F1DD2F` |
| link | `#F1DD2F` |
| button_bg | `#F1DD2F` |
| button_text | `#121212` |

**Using these colors**

- **Action color** `#F1DD2F` — 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 `#F1DD2F` — one role, not several (your action color).
- **accent** `#F1DD2F` — 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): `#1A1A1A` 35.5% · `#000000` 22.3% · `#6A6D66` 20.3% · `#B2B4A4` 11.6%

## Typography


| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 28px / 400 · lh 32px · tracking 0.21px |
| h2 | 22px / 600 · lh 26px |
| h3 | 20px / 400 · lh 28px · tracking 0.25px |
| body | 16px / 400 · lh 24px · tracking 0.5px |
| small | 14px / 400 · lh 20px · tracking 0.25px |
| eyebrow | 12px / 600 · tracking 2px |

- 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, 5px, 6px, 8px, 10px, 12px, 16px, 18px, 20px, 24px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 12px
- card: 50px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#F5C518` / `#000000` | none | 24px | 0px 16px 0px 16px | 500 14px / 0.28px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#0E63BE` | none | — | 0px 0px 0px 0px | 400 16px / 0.5px | none |

**States (measured, not guessed)**

- primary focus: outline `1px dashed rgb(0, 0, 0)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0.2) 0px 3px 1px -2px, rgba(0, 0, 0, 0.14) 0px 2px 2px 0px, rgba(0, 0, 0, 0.12) 0px 1px 5px 0px`
- card: `rgba(0, 0, 0, 0.12) 0px 0px 1px 0px`

## Motion
- durations: 150ms (dominant) · 200ms · 300ms
- easings: `ease` (dominant) · `ease-in-out`
- animated properties: opacity, color, stroke, transform

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: 3-col
- nav: 56px relative · bg #121212

## Motion choreography (measured)
Load order: `circle.ipc-loader__dot`×15 @0ms → `div.ipc-shoveler__arrow` @179ms → `div.ipc-reaction-summary`×16 @431ms → `div.sc-797f7458-0` @698ms
- `circle.ipc-loader__dot` ×15 — opacity 1→0.33 — 1250ms ease-in-out (delay -750ms) · loops
- stagger: `circle` ×111 — 150ms apart
- scroll reveal: 1 elements rest at opacity 0, translateY(100px), animate in over 0.3s ease (0 revealed during the drive).
- overlay palette (auto-opened): panel #1F1F1F · r 4px

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

## Components (measured)
- input: h 31.25px · r 0px · bg rgba(0, 0, 0, 0) · placeholder rgba(0, 0, 0, 0.54)
- link: #FFFFFF · no underline — hover #F5C518

## Responsive (measured)
- breakpoints: 480px · 600px · 640px · 1024px · 1280px
- 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.
