Decoded design system

eBay Mobile's decoded design system: background #FFFFFF, text #191919, accent #751619, link #707070, primary #751619; type scale h1 36px / h2 30px / body 14px; 4px spacing base; 12px base radius. The single interactive/action color is #0968F6 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #0968F6 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent are all #751619 — one role, not several (the action color).
• accent #751619 — accent for emphasis — keep it rare on the page.
• link #707070 — reads as a neutral UI color, not a link accent — verify against the reference (action = #0968F6).

# eBay Mobile — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F1F1F1` |
| border | `#DCDCDC` |
| text | `#191919` |
| text_muted | `#707070` |
| primary | `#751619` |
| accent | `#751619` |
| link | `#707070` |
| button_bg | `#0968F6` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#0968F6` — 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 `#751619` — one role, not several.
- **accent** `#751619` — accent for emphasis — keep it rare on the page.
- **link** `#707070` — reads as a neutral UI color, not a link accent — verify against the reference (action = #0968F6).
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 26.9% · `#191919` 26.2% · `#0968F6` 20% · `#063174` 9.2%

## Typography

- Heading: **Market Sans** _(free fallback: Newsreader)_
- Body: **Market Sans** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 36px / 700 · lh 46px |
| h2 | 30px / 700 · lh 40px |
| h3 | 24px / 700 · lh 32px |
| body | 14px / 400 · lh 20px |
| small | 13px / 400 |

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

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 10px, 12px, 14px, 16px, 20px, 28px, 32px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 44px
- card: 16px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#0968F6` / `#FFFFFF` | 1px solid rgb(9, 104, 246) | 44px | 0px 20px 0px 20px | 700 14px | none |

**States (measured, not guessed)**

- primary hover: background `#382AEF`
- primary focus: outline `2px solid rgb(16, 16, 16)`
- transition: `background-color 0.2s ease-in-out`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0.24) 0px 2px 2px 0px, rgba(0, 0, 0, 0.12) 0px 0px 2px 0px`
- card: `rgba(0, 0, 0, 0.07) 0px 4px 12px 0px`

## Motion
- durations: 150ms (dominant) · 167ms · 333ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `cubic-bezier(0.3, 0, 0.7, 1)`
- animated properties: opacity, scale, transform, 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.

- scroll reveal: 22 elements rest at opacity 0, animate in over 0.167s cubic-bezier(0.3, 0, 0.7, 1) (0 revealed during the drive).

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

## Components (measured)
- input: h 40px · r 44px 0px 0px 44px · bg #FFFFFF · placeholder #707070
- link: #FFFFFF · underline

## Responsive (measured)

- mobile (390px): hero 28px · body 14px · 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.
