# Threejs

> Extracted from [https://threejs.org/](https://threejs.org/) 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

Threejs uses a light canvas (#FFFFFF) with a palette led by #049EF4. Type is set in **Roboto Mono** (mono), with ?px body text. Layout: fluid container, none-detected navigation, 1 sections. Built with google-tag-manager, github-pages, fastly.

## 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 | 86.2% | `--background-color` |
| `on-surface` | `#444444` | 0.387 0 0 | text | 9.7% | `--text-color` |
| `primary` | `#049EF4` | 0.674 0.166 244.2 | accent | 3.8% | `--color-blue` |
| `border-color` | `#E8E8E8` | 0.931 0 0 | other | 0.38% | `--border-color` |

Contrast: text on background 9.74:1, accent 2.92:1.

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

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Roboto Mono** | mono | 400, 500 | 100.0% | webfont |

Scale (px): 13.5, 15, 18.  Body ?px at line-height normal; display 18px with tracking 0em. Headings are sentence case. On a 390px viewport the body is ?px and display 18px.

## Layout

Spacing has no reliable single base unit; the most used steps are 2, 6, 12, 16, 18, 20, 300px. Content sits in a fluid container on a 6-column grid. Text density 0.032 (text area / page area).

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

1. **footer** (6270px, bg #FFFFFF)

## Elevation & Depth

Style: flat. Most used shadows:

- `rgba(0, 0, 0, 0.15) 0px 0px 4px 0px`

## Shapes

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

## Do's and Don'ts

- Do reserve `#049EF4` for primary actions and highlights; it covers only 3.8% of the painted page.
- Don't introduce font weights beyond 400, 500.
- Don't add drop shadows; depth comes from tone and borders.
- Do keep corners at 4px for most controls.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.

Full per-field provenance is in `spec.json`.
