Decoded design system

Vercel's decoded design system: background #FAFAFA, text #171717, accent #0072F5, link #4D4D4D, primary #0072F5; type scale h1 64px / h2 56px / body 24px; 4px spacing base; 6px base radius. The single interactive/action color is #171717 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #171717 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent are all #0072F5 — one role, not several (the action color).
• accent #0072F5 — accent for emphasis — keep it rare on the page.
• link #4D4D4D — reads as a neutral UI color, not a link accent — verify against the reference (action = #171717).
• secondary #FBEEE7 — 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.

# Vercel — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FAFAFA` |
| surface | `#ECECEC` |
| border | `#D7D7D7` |
| text | `#171717` |
| text_muted | `#6D6D6D` |
| primary | `#0072F5` |
| accent | `#0072F5` |
| link | `#4D4D4D` |
| secondary | `#FBEEE7` |
| button_bg | `#171717` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#171717` — 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 `#0072F5` — one role, not several.
- **accent** `#0072F5` — accent for emphasis — keep it rare on the page.
- **link** `#4D4D4D` — reads as a neutral UI color, not a link accent — verify against the reference (action = #171717).
- **secondary** `#FBEEE7` — 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): `#FAFAFA` 95.3% · `#666666` 2.5% · `#E7E7E7` 2.1%

## Typography

- Heading: **GeistSans** _(free fallback: Newsreader)_
- Body: **GeistSans** _(free fallback: Newsreader)_
- Mono: **Geist Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 64px / 400 · lh 64px · tracking -3.84px |
| h2 | 56px / 450 · lh 56px · tracking -3.36px |
| body | 24px / 450 · lh 32px · tracking -0.96px |
| small | 16px / 500 · lh 24px |

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

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 12px, 16px, 20px, 24px, 32px, 40px — snap all gaps/padding to these

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

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#171717` / `#FFFFFF` | none | 6px | 0px 6px 0px 6px | 500 14px | none |
| secondary | `#FFFFFF` / `#171717` | none | 6px | 0px 6px 0px 6px | 500 14px | none |

**States (measured, not guessed)**

- primary hover: background `#383838`
- secondary hover: background `#F2F2F2`
- transition: `all 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 100ms (dominant) · 150ms · 200ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `cubic-bezier(0, 0, 0.2, 1)`
- animated properties: color, background-color, border-color, outline-color

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 |
|-------|-------|
| `--geist-cyan` | `#50e3c2` |
| `--geist-warning` | `#f5a623` |
| `--geist-error` | `#e00` |
| `--ds-black` | `lab(0% 0 0)` |
| `--ds-white` | `lab(100% 0 0)` |
| `--ds-background-100` | `hsla(0, 0%, 100%, 1)` |
| `--ds-background-200` | `hsla(0, 0%, 98%, 1)` |
| `--ds-gray-100` | `hsla(0, 0%, 95%, 1)` |
| `--ds-gray-200` | `hsla(0, 0%, 92%, 1)` |
| `--ds-gray-300` | `hsla(0, 0%, 90%, 1)` |
| `--ds-gray-400` | `hsla(0, 0%, 92%, 1)` |
| `--ds-gray-500` | `hsla(0, 0%, 79%, 1)` |

_…and 108 more measured on the page._

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

## Layout (measured)
- container max 961px · common grid: 12-col
- nav: 64px sticky

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 1108 | 2418 | — | — | 0/0 | — |
| 3734 | 718 | — | — | 0/0 | — |
| 3871 | 580 | 12 | 20 | 0/0 | — |

## Motion choreography (measured)
Load order: `svg.pointer-events-none` @0ms → `div.pointer-events-none` @1ms
- `svg.pointer-events-none` — opacity 0→1 — 300ms cubic-bezier(0.4, 0, 0.2, 1)
- `div.pointer-events-none` — opacity 1→0 — 300ms cubic-bezier(0, 0, 0.2, 1)
- scroll reveal: 4 elements rest at opacity 0, animate in over 200ms (0 revealed during the drive).

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

## Themes (both measured)
- dark counterpart: bg `#000000` · text `#EDEDED`
- tokens that flip between modes:
  - `--geist-error`: `#e00` → `red`
  - `--ds-background-100`: `hsla(0, 0%, 100%, 1)` → `hsla(0, 0%, 4%, 1)`
  - `--ds-background-200`: `hsla(0, 0%, 98%, 1)` → `hsla(0, 0%, 0%, 1)`
  - `--ds-gray-100`: `hsla(0, 0%, 95%, 1)` → `hsla(0, 0%, 10%, 1)`
  - `--ds-gray-200`: `hsla(0, 0%, 92%, 1)` → `hsla(0, 0%, 12%, 1)`
  - `--ds-gray-300`: `hsla(0, 0%, 90%, 1)` → `hsla(0, 0%, 16%, 1)`
  - `--ds-gray-400`: `hsla(0, 0%, 92%, 1)` → `hsla(0, 0%, 18%, 1)`
  - `--ds-gray-500`: `hsla(0, 0%, 79%, 1)` → `hsla(0, 0%, 27%, 1)`

## Responsive (measured)
- breakpoints: 400px · 600px · 640px · 768px · 960px · 1200px
- 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.
