# Dub Design System

## Overview

Dub describes itself as: “Dub is the modern link attribution platform for short links, conversion tracking, and affiliate programs.” The interface is light, built on **White (#FFFFFF)** with **Slate (#737373)** text and almost no color: actions are carried by contrast, not hue.

Type is set in **satoshi** and **Inter**, with **GeistMono** for code. Headlines run large; body text is 16px. Depth comes from soft drop shadows. Corners are mostly 8px.

Measured from [dub.co](https://dub.co/) on October 21, 2026 at 1440×900 and 390×844 from 416 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 17 roles, plus gradient stops #F97316.

- **White (#FFFFFF):** Page background, seen 17 times. Token `background`, CSS `--tw-ring-offset-color`.
- **Slate (#737373):** Primary text and headings, seen 51 times. Token `on-surface`.
- **Charcoal (#171717):** Headings and emphasis, seen 38 times. Token `on-surface-strong`.
- **Graphite (#262626):** Secondary text, seen 18 times. Token `on-surface-variant`.
- **Slate (#525252):** Muted text and metadata, seen 8 times. Token `on-surface-muted`.
- **Snow (#FAFAFA):** Raised areas one step from the page, seen 7 times. Token `surface-container-low`.
- **Snow (#F5F5F5):** Cards and panels, seen 15 times. Token `surface-container`.
- **Mist (#E5E5E5):** Hover and pressed fills, seen 2 times. Token `surface-container-high`.
- **White 20% (#FFFFFF33):** Translucent fill for cards and controls, seen 1 time. Token `overlay`.
- **Mist (#E5E5E5):** Borders and dividers, seen 49 times. Token `outline`.
- **Near Black 5% (#0000000D):** Secondary dividers, seen 9 times. Token `outline-variant`.
- **Near Black (#000000):** Primary buttons and calls to action, seen 16 times. Token `primary`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Light Violet (#C084FC):** Most used accent color, seen 5 times. Token `secondary`.
- **Green (#4ADE80):** Most used accent color, seen 5 times. Token `tertiary`.
- **Dark Green (#16A34A):** Success and positive states, seen 3 times. Token `success`.
- **Red (#DC2626):** Errors and destructive states, seen 1 time. Token `error`.

## Typography

**satoshi**, **Inter** and **GeistMono** (monospace) share the interface. Fallback stack: `satoshi, satoshi Fallback, system-ui, sans-serif`.

- **headline-display:** satoshi 48px at weight 500, line height 1 (30px on mobile). Page title (h1).
- **headline-lg:** satoshi 36px at weight 500, line height 1.11. Section headings (h2).
- **headline-md:** Inter 30px at weight 400, line height 1.38. Sub-section headings.
- **headline-sm:** Inter 24px at weight 400, line height 1.33. Card and feature titles.
- **body-md:** Inter 16px at weight 400, line height 1.5. Body text.
- **body-lg:** Inter 18px at weight 400, line height 1.56. Lead paragraphs.
- **body-sm:** Inter 14px at weight 400, line height 1.43. Secondary and small text.
- **caption:** Inter 12px at weight 400, line height 1.33. Captions and fine print.
- **label-md:** Inter 14px at weight 500, line height 1.43. Buttons, navigation and labels.
- **label-sm:** Inter 12px at weight 500, line height 1.33. Small labels and badges.
- **code:** GeistMono 14px at weight 400, line height 1.43. Code and technical values.

## Layout

Spacing is mostly on a 4px grid (85% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** xs 4px, sm 8px, md 16px, lg 20px, xl 48px.
- **Gaps:** 8px is the most common gap in flex and grid layouts.
- **Breakpoints:** 280px, 281px, 360px, 420px, 450px, 640px, 768px, 900px, 1024px, 1280px, 1400px.

## Elevation & Depth

Raised elements use soft drop shadows. The most used recipes:

- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.05) 0px 1px 2px 0px`

## Shapes

Most elements use 8px corners. Measured radii, most used first:

- **lg (8px):** 132 elements.
- **xl (12px):** 32 elements.
- **sm (4px):** 28 elements.
- **full (9999px):** 20 elements.
- **md (6px):** 16 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“Sign up”):** #000000 fill, #FFFFFF text, 14px/400, 8px radius, padding 0px 16px, border 1px solid #000000.
- **button-outline (“CASE STUDY”):** #F5F5F5 fill, #0A0A0A text, 16px/400, 12px radius, padding 0px.
- **button-ghost (“Conversion Analytics”):** #F5F5F5 fill, #525252 text, 16px/400, 8px radius, padding 8px 12px.
- **button-ghost-hover:** background #F5F5F5, text #262626 on hover.
- **link:** transparent fill, #737373 text, padding 0px.

## Do's and Don'ts

- Do use #FFFFFF for the page and lift surfaces in small steps: #FAFAFA, #F5F5F5, #E5E5E5.
- Do keep text in 4 levels: #737373, #171717, #262626, #525252.
- Do let contrast carry emphasis; primary actions use #000000 on #FFFFFF.
- Do reuse the measured spacing steps (8px, 16px, 20px).
- Do use 8px corners on most elements; larger surfaces also use 12px, 4px and 6px.
- Don't introduce new font families beyond satoshi, Inter and GeistMono.
- Don't add saturated accent colors; the measured palette is almost entirely neutral.
- Don't make interface transitions slower than 0.5s.

## Motion

Interface transitions are quick: 0.15s, 0.5s, 0.075s, 0.1s.

- **Easing:** `cubic-bezier(0.4, 0, 0.2, 1)`, `ease-out`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
