# Nautilus

> Extracted from [https://nautil.us/](https://nautil.us/) on 2026-11-12 by Emblematic. Every value below was read from the rendered DOM (computed styles, `document.fonts`, and the fonts Chrome actually used to paint text), not estimated from pixels. When the YAML front matter and this prose disagree, the YAML wins. Copy values from this file exactly; don't transcribe them from memory. Don't copy logos, imagery, illustrations or marketing copy.

## Overview

Nautilus uses a light canvas (#FFFFFF) with a palette led by #07863C. Type is set in **Freight Sans**, **Freight Display** (display), with 16px body text. Layout: 1280px container, top-sticky navigation, 7 sections. Built with next.js, wordpress.

## Colors

Area-weighted from painted backgrounds, text and borders on the 1440px light capture. Roles are inferred from usage (largest background, most text, interactive fills). Every hex is an exact computed value; a role marked *unverified* is a best guess that has not passed review, so its canonical token (e.g. `primary`) is left out of the front matter.

| Token | Hex | OKLCH | Role | Share of paint | CSS variable |
|---|---|---|---|---|---|
| `background` | `#FFFFFF` | 1 0 0 | bg | 76.4% | `--cc-bg` |
| `primary` | `#07863C` | 0.543 0.148 149.7 | accent | 9.8% | `--wp--custom--color--primary` |
| `on-surface` | `#191919` | 0.213 0 0 | text | 6.8% | `--wp--custom--color--gray--90` |
| `wp--custom--color--opinion` | `#FFF5CD` | 0.968 0.053 95.6 | other | 6.0% | `--wp--custom--color--opinion` |
| `wp--custom--color--black` | `#000000` | 0 0 0 | other | 0.88% | `--wp--custom--color--black` |

Declared brand/accent tokens: `--wp--custom--color--brand--secondary--base` = `#FFCD05` (declared, not painted on this page).

Contrast: text on background 17.58:1, accent 4.68:1.

The site responds to `prefers-color-scheme: dark`; the `-dark` tokens hold the dark-mode roles.

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Freight Sans** | body | 400, 600 | 82.6% | webfont |
| **Freight Display** | display | 600 | 17.4% | webfont |

Scale (px): 12, 14, 16, 20, 24, 32, 40. Effective ratio ≈ 1.257 (close to a major third). Body 16px at line-height 1.55; display 40px with tracking 0em. Headings are title case. On a 390px viewport the body is 16px and display 36px.

## Layout

Spacing follows a 4px base unit; the most used steps are 8, 10, 12, 16, 20, 24, 32, 80px. Sections open with about 111px of space before their first line of text. Content sits in a 1280px container on a 3-column grid. Text density 0.065 (text area / page area).

Section order (desktop). Kinds below the review threshold are shown as *section*:

1. **nav** (165px, bg #FFFFFF)
2. **hero** — “What’s All That Coffee Doing to Your Gut?” (1814px, bg #FFFFFF)
3. **testimonials** — “Read Stories from Our Newest Print Issue: The Stupid Issue” (583px, bg #FFFFFF)
4. **testimonials** — “Get the Nautilus newsletter” (2963px, bg #FFFFFF)
5. **testimonials** — “Our Planet’s Lungs Are Suffering” (2598px, bg #FFFFFF)
6. **testimonials** — “Essential Reading in an Era of AI Doomsaying” (2049px, bg #FFFFFF)
7. **footer** (517px, bg #FFFFFF)

## Elevation & Depth

Style: flat. Most used shadows:

- `rgba(0, 0, 0, 0.45) 0px 0px 2px 0px`

## Shapes

Dominant corner radius 4px; radii in use: 4px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#07863C`, textColor `#FFFFFF`, rounded `4px`, padding `8px 18px`, height `40.8px`, fontFamily `Freight Sans`, fontSize `16px`, fontWeight `400` (e.g. “Subscribe”)
- **input**: rounded `4px`, height `56px`, padding `16px 16px`, backgroundColor `#FAFAFA`, border `1px solid #4D4D4D`

## Do's and Don'ts

- Do reserve `#07863C` for primary actions and highlights; it covers only 9.8% of the painted page.
- Do set body copy in Freight Sans at 16px / 1.55.
- Do use Freight Display only for display sizes, not for body text.
- Don't introduce font weights beyond 400, 600.
- Don't add drop shadows; depth comes from tone and borders.
- Do keep corners at 4px for most controls.
- Do snap spacing to multiples of 4px.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
