Decoded design system

Google's decoded design system: background #FFFFFF, text #1F1F1F, accent #1A73E8, link #1A73E8, primary #0B57D0; type scale h1 28px / h2 14px / body 14px; 4px spacing base; 16px 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.
• primary, button_bg are all #0B57D0 — one role, not several (the action color).
• accent, link are all #1A73E8 — one role, not several (the action color).
• accent #1A73E8 — accent for emphasis — keep it rare on the page.
• secondary #1A0DAB — 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.

# Google — Design System

> light, minimalist, low, custom — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F1F1F1` |
| border | `#DDDDDD` |
| text | `#1F1F1F` |
| text_muted | `#747474` |
| primary | `#0B57D0` |
| accent | `#1A73E8` |
| link | `#1A73E8` |
| secondary | `#1A0DAB` |
| button_bg | `#0B57D0` |
| button_text | `#FFFFFF` |

**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.
- `primary`, `button_bg` are all `#0B57D0` — one role, not several (your action color).
- `accent`, `link` are all `#1A73E8` — one role, not several.
- **accent** `#1A73E8` — accent for emphasis — keep it rare on the page.
- **secondary** `#1A0DAB` — 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): `#666666` 46.9% · `#FFFFFF` 44.4% · `#C7C8CA` 6% · `#97989C` 1.4%

## Typography

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

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 28px / 400 · lh 36px |
| body | 14px / 400 · lh 20px |
| small | 13px / 400 · lh 24px |

- 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). Roboto — free, on Google.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 5px, 6px, 8px, 10px, 15px, 16px, 20px, 32px, 34px — snap all gaps/padding to these

## Radius
- base: 16px
- button: 100px
- card: 100px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#0B57D0` / `#FFFFFF` | none | 100px | 10px 12px 10px 12px | 500 14px | none |
| secondary | `#F8F9FA` / `#3C4043` | 1px solid rgb(248, 249, 250) | 8px | 0px 16px 0px 16px | 500 14px | none |

**States (measured, not guessed)**

- primary hover: box-shadow `rgba(0, 0, 0, 0.3) 0px 1px 2px 0px, rgba(0, 0, 0, 0.15) 0px 1px 3px 1px`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.2) 0px 2px 10px 0px`

## Motion
- durations: 50ms (dominant) · 150ms · 200ms
- easings: `linear` (dominant) · `ease-in-out`
- animated properties: opacity, transform, visibility, height

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 |
|-------|-------|
| `--COEmY` | `#1f1f1f` |
| `--xhUGwc` | `#fff` |
| `--vZe0jb` | `#a3c9ff` |
| `--nwXobb` | `#a3c9ff` |
| `--VuZXBd` | `#001d35` |
| `--uLz37c` | `#545d7e` |
| `--jINu6c` | `#001d35` |
| `--TyVYld` | `#0b57d0` |
| `--ZEpPmd` | `#a3c9ff` |
| `--QWaaaf` | `#a3c9ff` |
| `--DEeStf` | `#f5f8ff` |
| `--TSWZIb` | `#e5edff` |

_…and 82 more measured on the page._

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

## Layout (measured)
- nav: 51px

## Motion choreography (measured)
- `div.eruMcc` — filter blur(1px)→blur(3px) — 1000ms
- `div.fZhNMe` — opacity 0→1 — 1000ms cubic-bezier(0, 0, 0, 1)
- overlay dropdown (auto-opened): panel #FFFFFF · r 0px · shadow rgba(0, 0, 0, 0.2) 0px 2px 10px 0px

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

## Components (measured)
- input: h 28px · r 0px · bg rgba(0, 0, 0, 0) · placeholder #636363

## Responsive (measured)
- breakpoints: 360px · 479px · 569px
- 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.
