Decoded design system

Windsurf's decoded design system: background #F7F6F5, text #000000, accent #317CFF, link #191919, primary #2200FF; type scale h1 64px / h2 40px / body 16px; 4px spacing base; 0px base radius. The single interactive/action color is #191919 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #191919 — the single interactive color; only on things you click or must notice, never large fills.
• accent, secondary are all #317CFF — one role, not several (the action color).
• link, button_bg are all #191919 — one role, not several (the action color).
• accent #317CFF — accent for emphasis — keep it rare on the page.
• primary #2200FF — a brand color — but the call-to-action uses #191919, not this.

# Windsurf — Design System

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

## Colors

| button_bg | `#191919` |

**Using these colors**

- **Action color** `#191919` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `secondary` are all `#317CFF` — one role, not several.
- `link`, `button_bg` are all `#191919` — one role, not several (your action color).
- **accent** `#317CFF` — accent for emphasis — keep it rare on the page.
- **primary** `#2200FF` — a brand color — but the call-to-action uses #191919, not this.
- **Page coverage** (full-page screenshot pixels): `#F7F6F5` 95.7% · `#B8B8BA` 4.3%

## Typography

- Heading: **NB International Pro** _(free fallback: Newsreader)_
- Body: **NB International Pro** _(free fallback: Newsreader)_
- Mono: **Geist Mono**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 64px / 400 · lh 64px · tracking -1.92px |
| h2 | 40px / 400 · lh 42px · tracking -1.2px |
| h3 | 32px / 400 · lh 38px · tracking -0.64px |
| body | 16px / 400 · lh 22px |
| small | 15px / 400 · lh 20px |
| eyebrow | 12px / 400 · tracking 0.36px |

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

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 5px, 6px, 8px, 10px, 12px, 14px, 16px, 20px — snap all gaps/padding to these
- section rhythm: 48px top/bottom padding per section (measured)

## Radius
- base: 0px
- button: 2px
- card: 6px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#191919` / `#FFFFFF` | none | 2px | 6px 12px 5px 12px | 400 14px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#191919` | 1px solid rgb(25, 25, 25) | 2px | 5px 11px 4px 11px | 400 14px | none |

**States (measured, not guessed)**

- primary focus: outline `1px auto rgb(16, 16, 16)`
- transition: `opacity 0.15s cubic-bezier(0, 0, 0.2, 1)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0.05) 0px 1px 2px 0px`
- card: `rgba(0, 0, 0, 0.06) 0px 0px 3px 0px, rgba(0, 0, 0, 0.08) 0px 0px 0px 0.5px`
- overlay: `rgba(0, 0, 0, 0.14) 0px 8px 24px -6px, rgba(0, 0, 0, 0.06) 0px 2px 6px 0px`

## Motion
- durations: 150ms (dominant) · 250ms · 200ms
- easings: `ease` (dominant) · `cubic-bezier(0.4, 0, 0.2, 1)`
- animated properties: background-color, opacity, transform, color

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

_…and 101 more measured on the page._

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

## Layout (measured)

## Motion choreography (measured)
Load order: `span.truncate`×6 @0ms → `span`×2 @271ms → `span.inline-block` @271ms → `span`×14 @1311ms → `div.flex`×5 @2511ms → `span` @2511ms
- scroll reveal: 5 elements rest at opacity 0, translateY(8px), animate in over 0.45s ease (2 revealed during the drive).

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

## Components (measured)
- input: h 29.75px · r 0px · bg rgba(0, 0, 0, 0) · placeholder oklab(0.213404 0.00000968575 0.00000427663 / 0.5)
- card ×3: pad 8px 8px 8px 8px · r 10px · bg rgba(0, 0, 0, 0)
  - hover: font-weight `400` · letter-spacing `normal`

## Responsive (measured)
- breakpoints: 640px · 768px · 1024px · 1400px
- mobile (390px): hero 40px · body 16px · nav: hamburger

## 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.
