Decoded design system

Chromewebstore's decoded design system: background #FFFFFF, text #1F1F1F, accent #0B57D0, link #0B57D0, primary #2962FF; type scale h1 22px / h2 16px / body 14px; 4px spacing base; 6px base radius. The single interactive/action color is #0B57D0 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #0B57D0 — the single interactive color; only on things you click or must notice, never large fills.
• accent, link, button_bg are all #0B57D0 — one role, not several (the action color).
• accent #0B57D0 — 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.
• primary #2962FF — a brand color — but the call-to-action uses #0B57D0, not this.
• secondary #D3E3FD — 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.

Typography

• Heading: Google Sans
• Body: Arial
• h1: 22px
• h2: 16px
• body: 14px

Spacing

• base unit: 4px
• scale: 8px, 12px, 16px, 20px, 24px, 34px, 48px

Radii

• base: 6px
• button: 20px

Motion

Micro-interactions run at 350ms (dominant) with cubic-bezier(0.4, 0.1, 0.5, 1.4).

• durations: 350ms · 75ms
• easings: cubic-bezier(0.4, 0.1, 0.5, 1.4) · linear
• animated properties: border-radius, opacity

Native design tokens

Responsive (measured)

• mobile (390px): hero 22px · nav inline

Install it

Drop this measured system into any shadcn/Tailwind project in one command:

# Chromewebstore — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F1F1F1` |
| border | `#DDDDDD` |
| text | `#1F1F1F` |
| text_muted | `#747474` |
| primary | `#2962FF` |
| accent | `#0B57D0` |
| link | `#0B57D0` |
| secondary | `#D3E3FD` |
| button_bg | `#0B57D0` |
| button_text | `#000000` |

**Using these colors**

- **Action color** `#0B57D0` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `link`, `button_bg` are all `#0B57D0` — one role, not several (your action color).
- **accent** `#0B57D0` — 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.
- **primary** `#2962FF` — a brand color — but the call-to-action uses #0B57D0, not this.
- **secondary** `#D3E3FD` — 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` 92.3% · `#BBBEC0` 2% · `#98A0AC` 1.9% · `#CCCCCC` 1.3%

## Typography

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

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 22px / 400 · lh 28px |
| body | 14px / 400 · lh 20px · tracking 0.2px |
| small | 12px / 400 |

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

> **Fonts —** Google Sans may be proprietary — safe free fallback: Newsreader (Google Fonts). Arial — system font, no web load needed.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 8px, 12px, 16px, 20px, 24px, 34px, 48px — snap all gaps/padding to these

## Radius
- base: 6px
- button: 20px
- card: 20px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#0B57D0` / `#000000` | none | 20px | 0px 24px 0px 24px | 400 13.3333px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#000000` | 1px solid rgb(116, 119, 117) | 20px | 0px 24px 0px 16px | 400 13.3333px | none |

**States (measured, not guessed)**

- transition: `border-radius 0.35s cubic-bezier(0.4, 0.1, 0.5, 1.4)`

## Motion
- durations: 350ms (dominant) · 75ms
- easings: `cubic-bezier(0.4, 0.1, 0.5, 1.4)` (dominant) · `linear`
- animated properties: border-radius, opacity

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)

| Token | Value |
|-------|-------|
| `--boq-chrometransition-background` | `#eee` |

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Components (measured)
- link: #0B57D0 · underline

## Responsive (measured)
- mobile (390px): hero 22px · 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.
