Tokens

Browserbase's decoded design system: background #FFFFFF, text #000000, accent #000000, link #C5D3E8, primary #E1E9F2; type scale h1 16px / h2 45px / body 20px; 4px spacing base; 0px base radius. The single interactive/action color is #000000 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Browserbase — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#E1E9F2` |
| accent | `#000000` |
| link | `#C5D3E8` |
| secondary | `#FF4500` |
| button_bg | `#000000` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#000000` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `button_bg` are all `#000000` — one role, not several (your action color).
- **accent** `#000000` — 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** `#E1E9F2` — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #000000).
- **link** `#C5D3E8` — fails contrast on the background (~1.5:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#FF4500` — 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): `#CFDAE7` 47.3% · `#FFFFFF` 27.6% · `#B86E3A` 13.7% · `#362019` 11.5%

## Typography

- Heading: **gtStandardMono** _(free fallback: JetBrains Mono)_
- Body: **gtStandardMono** _(free fallback: JetBrains Mono)_
- Mono: **gtStandardMono**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 45px / 500 · lh 52px · tracking -0.9px |
| h2 | 36px / 500 · lh 38px · tracking -0.36px |
| h3 | 24px / 500 · lh 25px · tracking -0.24px |
| body | 16px / 500 · lh 16px · tracking 0.16px |
| small | 14px / 500 · lh 17px · tracking 0.42px |
| eyebrow | 14px / 500 · tracking 0.84px |

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

> **Fonts —** gtStandardMono may be proprietary — safe free fallback: JetBrains Mono (Google Fonts).

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 7px, 8px, 10px, 12px, 14px, 16px, 18px, 24px, 32px — snap all gaps/padding to these
- section rhythm: 80px top/bottom padding per section (measured)

## Radius
- base: 0px
- button: 99px
- card: 99px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#E1E9F2` / `#000000` | none | 99px | 14px 18px 14px 18px | 500 16px / 0.16px | none |
| secondary | `#000000` / `#FFFFFF` | none | 99px | 14px 18px 14px 18px | 500 16px / 0.16px | none |

**States (measured, not guessed)**

- primary hover: border-radius `0px` · background `#F0F4F8`
- primary focus: outline `3px solid rgb(0, 0, 0)`
- secondary hover: border-radius `0px` · background `#333132`
- transition: `border-radius 0.3s cubic-bezier(0.3, 0, 0.15, 1)`

## Motion
- durations: 200ms (dominant) · 300ms · 100ms
- easings: `cubic-bezier(0.3, 0, 0.15, 1)` (dominant) · `ease-in-out`
- animated properties: background-color, border-radius, color, transform

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 |

_…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 1280px · common grid: 12-col
- nav: 52px sticky · bg #FFFFFF

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 113 | 715 | — | — | 0/0 | — |

## Motion choreography (measured)
- scroll reveal: 2 elements rest at translateY(59px) (2 revealed during the drive).

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

## Components (measured)
- link: #000000 · no underline

## Responsive (measured)
- breakpoints: 400px · 600px · 960px · 1120px · 1280px · 1408px
- mobile (390px): 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.
