# Ornn Design System

## Overview

Ornn describes itself as: “Compute trades in the world’s most opaque market. Ornn makes it something you can price, finance, and hedge with confidence.” The interface is light, built on **White (#FFFFFF)** with **Near Black (#000000)** text and almost no color: actions are carried by contrast, not hue.

Type is set in **FK Roman Standard Regular** and **PP Neue Montreal Medium**. Headlines run large with tight negative tracking; body text is 20px. The surface language is flat. Corners are mostly 80px.

Measured from [ornn.com](https://ornn.com/) on November 7, 2026 at 1440×900 and 390×844 from 189 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 10 roles.

- **White (#FFFFFF):** Page background, seen 1 time. Token `background`.
- **Near Black (#000000):** Primary text and headings, seen 4 times. Token `on-surface`.
- **Charcoal (#141414):** Secondary text, seen 2 times. Token `on-surface-variant`.
- **Gray (#808080):** Muted text and metadata, seen 7 times. Token `on-surface-muted`.
- **Gray (#A6A6A6):** Subtle text and placeholders, seen 2 times. Token `on-surface-subtle`.
- **Mist (#F3F3F3):** Raised areas one step from the page, seen 2 times. Token `surface-container-low`.
- **White 24% (#FFFFFF3D):** Borders and dividers, seen 2 times. Token `outline`.
- **Near Black 8% (#00000014):** Secondary dividers, seen 1 time. Token `outline-variant`.
- **Near Black (#000000):** Primary actions (the main text color; the palette is monochrome), seen 8 times. Token `primary`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.

## Typography

**FK Roman Standard Regular**, **PP Neue Montreal Medium** and **sans-serif** share the interface. Fallback stack: `FK Roman Standard Regular, FK Roman Standard Regular Placeholder, sans-serif`. Other loaded fonts: FK Roman Standard Light.

- **display-hero:** FK Roman Standard Regular 72px at weight 400, line height 0.96, tracking -0.075em (44px on mobile). Oversized hero statements.
- **headline-display:** FK Roman Standard Regular 58px at weight 400, line height 1.1, tracking -0.075em (40px on mobile). Page title (h1).
- **headline-lg:** PP Neue Montreal Medium 22px at weight 500, line height 1.15, tracking -0.01em. Section headings (h2).
- **body-md:** PP Neue Montreal Medium 20px at weight 500, line height 1.35, tracking -0.01em. Body text.
- **body-sm:** sans-serif 12px at weight 400. Secondary and small text.
- **label-md:** PP Neue Montreal Medium 16px at weight 500, line height 1.2, tracking -0.01em. Buttons, navigation and labels.
- **label-sm:** PP Neue Montreal Medium 14px at weight 500, line height 1.2. Small labels and badges.

## Layout

Spacing is mostly on a 4px grid (86% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** sm 8px, md 14px, lg 20px, xl 40px.
- **Sections:** 140px vertical padding between major sections.
- **Gaps:** 8px is the most common gap in flex and grid layouts.
- **Container:** content is capped at 1800px.
- **Page margin:** 40px on each side of full-width sections.
- **Breakpoints:** 809px, 809.98px, 810px, 1099px, 1099.98px, 1100px, 1199px, 1200px, 1727px, 1727.98px.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from tonal surface steps (#F3F3F3) and #FFFFFF3D borders.

## Shapes

Most elements use 80px corners. Measured radii, most used first:

- **md (80px):** 36 elements.

## Components

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

- **button-outline (“Buy Compute Buy Compute Buy Comp”):** #F3F3F3 fill, #000000 text, 12px/400, 80px radius, padding 9px 20px.
- **link:** transparent fill, #F3F3F3 text, padding 0px.

## Do's and Don'ts

- Do use #FFFFFF for the page and lift surfaces in small steps: #F3F3F3.
- Do keep text in 4 levels: #000000, #141414, #808080, #A6A6A6.
- Do let contrast carry emphasis; primary actions use #000000 on #FFFFFF.
- Do set headlines in FK Roman Standard Regular with tight tracking (-0.075em).
- Do reuse the measured spacing steps (8px, 14px, 20px).
- Do use 80px corners on most elements.
- Don't use #808080 for body text; it reaches 3.95:1 on #FFFFFF. Keep it for large text or metadata.
- Don't use #A6A6A6 for body text; it reaches 2.43:1 on #FFFFFF. Keep it for large text or metadata.
- Don't add drop shadows for depth; use tonal surfaces.
- Don't introduce new font families beyond FK Roman Standard Regular, PP Neue Montreal Medium and sans-serif.
- Don't add saturated accent colors; the measured palette is almost entirely neutral.
- Don't make interface transitions slower than 0.2s.

## Motion

Interface transitions are quick: 0.2s.

- **Easing:** `cubic-bezier(0.44, 0, 0.56, 1)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
