# United Carriers Design System

## Overview

United Carriers describes itself as: “Freight forwarding, land transport, and customs brokerage, unified across APAC under one accountable team.” The interface is dark, built on **Near Black (#000000)** with **White (#FFFFFF)** text, and **Indigo (#0016CB)** as the main accent.

Type is set in **BT Steinhart** and **Helvetica Neue**. Headlines run large; body text is 24px. The surface language is flat. Controls are pill-shaped.

Measured from [unitedcarriers.com](https://unitedcarriers.com/) on November 5, 2026 at 1440×900 from 240 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 7 roles, plus gradient stops #0016CB.

- **Near Black (#000000):** Page background, seen 1 time. Token `background`, CSS `--_color---content--black<deleted|variable-6e7d8137-8713-9ff4-5cea-f92e6216a872>`.
- **White (#FFFFFF):** Primary text and headings, seen 8 times. Token `on-surface`, CSS `--_color---bg--main`.
- **Charcoal (#111111):** Raised areas one step from the page, seen 3 times. Token `surface-container-low`, CSS `--_color---border--highlight`.
- **Charcoal 20% (#11111133):** Borders and dividers, seen 3 times. Token `outline`, CSS `--_color---border--main`.
- **Indigo (#0016CB):** Brand accent (CSS variable), seen 24 times. Token `primary`, CSS `--_color---content--brand`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Vivid Orange (#FD6020):** Accent, seen 2 times. Token `secondary`.

## Typography

**BT Steinhart** and **Helvetica Neue** share the interface. Fallback stack: `BT Steinhart, Arial, sans-serif`. Other loaded fonts: BT Steinhart Mono.

- **headline-display:** BT Steinhart 80px at weight 700, line height 1.05, uppercase. Page title (h1).
- **headline-lg:** BT Steinhart 60px at weight 700, line height 1.05, uppercase. Section headings (h2).
- **body-md:** BT Steinhart 24px at weight 700, line height 1.25. Body text.
- **body-sm:** Helvetica Neue 23px at weight 500, line height 1.2. Secondary and small text.
- **label-md:** BT Steinhart 20px at weight 700, line height 1.1, uppercase. Buttons, navigation and labels.
- **label-sm:** Helvetica Neue 13px at weight 500, line height 1.2. Small labels and badges.

## Layout

Spacing does not follow a strict grid: 0% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 3.33px, sm 6.67px, md 13.33px, xl 33.33px.
- **Sections:** 133.33px vertical padding between major sections.
- **Gaps:** 16.67px is the most common gap in flex and grid layouts.
- **Breakpoints:** 479px, 767px, 768px, 991px, 992px, 2400px.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from tonal surface steps (#111111) and #11111133 borders.

## Shapes

Interactive controls are pill-shaped. Measured radii, most used first:

- **full (9999px):** 12 elements.

## Components

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

- **button-primary (“TALK WITH US”):** #FFFFFF fill, #111111 text, 13.3333px/400, 1440px radius, padding 0px.
- **button-ghost (“MENU CLOSE”):** transparent fill, #FFFFFF text, 13.3333px/400, padding 12.5px 4.17px 12.5px 33.33px.
- **link:** transparent fill, #111111 text, padding 0px.

## Do's and Don'ts

- Do use #000000 for the page and lift surfaces in small steps: #111111.
- Do use #0016CB as the brand accent: header, logo and key highlights.
- Do reuse the measured spacing steps (6.67px, 13.33px).
- Do make buttons and chips fully rounded (9999px).
- Don't add drop shadows for depth; use tonal surfaces.
- Don't introduce new font families beyond BT Steinhart and Helvetica Neue.
- Don't use #0016CB for large backgrounds or body text.
- Don't make interface transitions slower than 0.4s.

## Motion

Interface transitions are quick: 0.4s, 0.3s. Longer ambient animations run 3s.

- **Easing:** `ease`, `cubic-bezier(0.445, 0.05, 0.55, 0.95)`.
