Decoded design system

Runway's decoded design system: background #FFFFFF, text #404040, accent #2B22FA, link #FFFFFF, primary #6B7280; type scale h1 48px / h2 40px / body 14px; 4px spacing base; 6px base radius. The single interactive/action color is #F7F7F7 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #F7F7F7 — the single interactive color; only on things you click or must notice, never large fills.
• accent #2B22FA — accent for emphasis — keep it rare on the page.
• primary #6B7280 — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #F7F7F7).
• link #FFFFFF — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
• secondary #9CA3AF — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.

# Runway — Design System

> light, modern, medium, tailwind — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F3F3F3` |
| border | `#E2E2E2` |
| text | `#404040` |
| text_muted | `#888888` |
| primary | `#6B7280` |
| accent | `#2B22FA` |
| link | `#FFFFFF` |
| secondary | `#9CA3AF` |
| button_bg | `#F7F7F7` |
| button_text | `#0C0C0C` |

**Using these colors**

- **Action color** `#F7F7F7` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- **accent** `#2B22FA` — accent for emphasis — keep it rare on the page.
- **primary** `#6B7280` — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #F7F7F7).
- **link** `#FFFFFF` — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#9CA3AF` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 73.3% · `#161B2E` 8.2% · `#605D5C` 5.3% · `#9A999A` 4.6%

## Typography

- Heading: **abcNormal** _(free fallback: Newsreader)_
- Body: **abcNormal** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 48px / 400 · lh 48px · tracking -1.2px |
| h2 | 40px / 400 · lh 40px |
| h3 | 36px / 400 · lh 36px · tracking -0.9px |
| body | 14px / 600 · lh 20px |
| small | 13px / 400 · lh 17px · tracking -0.26px |

- Weight ladder: 400 · 450 · 500 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** abcNormal may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 10px, 15px, 16px, 20px, 24px, 28px, 40px — snap all gaps/padding to these
- section rhythm: 40px top/bottom padding per section (measured)

## Radius
- base: 6px
- button: 6px
- card: 15px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#F7F7F7` / `#0C0C0C` | none | 6px | 6px 10px 6px 10px | 600 14px | none |
| secondary | `#262626` / `#FFFFFF` | none | 4px | 4px 8px 4px 8px | 600 14px | none |

**States (measured, not guessed)**

- primary hover: background `#000000` · color `#FFFFFF`
- primary focus: box-shadow `rgb(255, 255, 255) 0px 0px 0px 2px, rgb(59, 130, 246) 0px 0px 0px 4px, rgba(0, 0, 0, 0) 0px 0px 0px 0px` · background `#262626` · color `#FFFFFF` · outline `2px solid rgba(0, 0, 0, 0)`
- secondary hover: background `#000000`
- transition: `all 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- overlay: `rgba(0, 0, 0, 0.3) 0px 30px 70px 0px`

## Motion
- durations: 200ms (dominant) · 150ms · 250ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `linear`
- animated properties: opacity, background-color, color, 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 1600px
- nav: 64px fixed · bg rgba(12, 12, 12, 0.95)

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 0 | 834 | — | — | 0/24 | — |
| 1110 | 635 | — | — | 0/0 | — |
| 1905 | 699 | — | — | 0/0 | — |
| 2779 | 1202 | — | — | 0/0 | — |
| 4157 | 595 | — | — | 0/0 | — |

## Motion choreography (measured)
Load order: `a.font-semibold`×3 @0ms → `a.font-semibold`×3 @1ms
- scroll reveal: 7 elements rest at opacity 0, animate in over 0.2s linear (0 revealed during the drive).

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

## Components (measured)
- link: #2A4EEF · no underline

## Responsive (measured)
- breakpoints: 640px · 768px · 1024px · 1280px · 1536px
- mobile (390px): hero 48px · 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.
