Decoded design system

IMDb Mobile's decoded design system: background #121212, text #000000, accent #F1DD2F, link #FFFFFF, primary #F1DD2F; type scale h1 28px / h2 22px / body 16px; 4px spacing base; 12px base radius. The single interactive/action color is #F5C518 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #F5C518 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent are all #F1DD2F — one role, not several (the action color).
• accent #F1DD2F — accent for emphasis — keep it rare on the page.
• link #FFFFFF — reads as a neutral UI color, not a link accent — verify against the reference (action = #F5C518).

# IMDb Mobile — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#121212` |
| surface | `#101010` |
| border | `#0F0F0F` |
| text | `#000000` |
| text_muted | `#060606` |
| primary | `#F1DD2F` |
| accent | `#F1DD2F` |
| link | `#FFFFFF` |
| button_bg | `#F5C518` |
| button_text | `#000000` |

**Using these colors**

- **Action color** `#F5C518` — 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` are all `#F1DD2F` — one role, not several.
- **accent** `#F1DD2F` — accent for emphasis — keep it rare on the page.
- **link** `#FFFFFF` — reads as a neutral UI color, not a link accent — verify against the reference (action = #F5C518).
- **Page coverage** (full-page screenshot pixels): `#1A1A1A` 35.5% · `#000000` 22.3% · `#6A6D66` 20.3% · `#B2B4A4` 11.6%

## Typography

- Heading: **Roboto**
- Body: **Roboto**

| 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.

> **Fonts —** Roboto — free, on Google.

## 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: 24px
- 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.

## 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.
