# Commercial Type Design System

## Overview

The interface is light, built on **Vivid Blue (#38A4FA)** with **Near Black (#000000)** text, and **Deep Purple (#5A0050)** as the main accent.

Type is set in **Styrene UI A**. Headlines run large; body text is 14.5px. Depth comes from soft drop shadows. Corners are square.

Measured from [commercialtype.com](https://commercialtype.com/) on November 4, 2026 at 1440×900 and 390×844 from 88 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 8 roles.

- **Vivid Blue (#38A4FA):** Page background, seen 1 time. Token `background`.
- **Near Black (#000000):** Primary text and headings, seen 14 times. Token `on-surface`.
- **White (#FFFFFF):** Secondary text, seen 11 times. Token `on-surface-variant`.
- **Deep Purple (#5A0050):** Brand color on large areas, seen 1 time. Token `primary`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Graphite (#323232):** High-contrast fills, seen 11 times. Token `inverse-surface`.
- **Light Teal (#78FFF0):** Accent on large areas, seen 1 time. Token `secondary`.
- **Red (#FF4B6C):** Accent on large areas. Token `tertiary`.

## Typography

**Styrene UI A** carries the whole interface. Fallback stack: `Styrene UI A, Arial, sans-serif`. Other loaded fonts: Styrene UI B, Action Grotesque Upright, Spectator Upright, Spectator Italic.

- **headline-display:** Styrene UI A 21px at weight 400, line height 1.4 (19.5px on mobile). Page title (h1).
- **body-md:** Styrene UI A 14.5px at weight 400, line height 1.4. Body text.
- **body-lg:** Styrene UI A 16.5px at weight 400, line height 1.4. Lead paragraphs.

## 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 2.09px, sm 6.26px, md 10.44px, lg 20.46px.
- **Gaps:** 20.88px is the most common gap in flex and grid layouts.
- **Page margin:** 20.88px on each side of full-width sections.
- **Breakpoints:** 640px, 641px, 768px, 769px, 1024px, 1280px, 1440px.

## Elevation & Depth

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

- `rgba(0, 0, 0, 0.35) 2.088px 2.088px 6.8904px 0px`
- `rgba(0, 0, 0, 0.25) 2.088px 2.088px 6.8904px 0px`

## Shapes

Corners are square. Measured radii, most used first:

- **none (0px):** measured.

## Components

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

- **button-primary (“Catalog”):** #323232 fill, #FFFFFF text, 20.88px/400, padding 0px 6.26px, shadow `rgba(0, 0, 0, 0.35) 2.088px 2.088px 6.8904px 0px`.
- **input-field:** transparent fill, #000000 text, 14.616px/400, padding 0px 2.92px, border 1px solid #000000.

## Do's and Don'ts

- Do use #38A4FA for the page.
- Do keep text in 2 levels: #000000, #FFFFFF.
- Do use #5A0050 as the brand accent: header, logo and key highlights.
- Do reuse the measured spacing steps (6.26px, 10.44px, 20.46px).
- Don't use #FFFFFF for body text; it reaches 2.67:1 on #38A4FA. Keep it for large text or metadata.
- Don't introduce new font families beyond Styrene UI A.
- Don't use #5A0050 for large backgrounds or body text.
- Don't make interface transitions slower than 0.3s.

## Motion

Interface transitions are quick: 0.15s, 0.3s.

- **Easing:** `ease`.
