# Lusion

> Extracted from [https://lusion.co/](https://lusion.co/) 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

Lusion uses a dark canvas (#2B2E3A) with a monochrome palette. Type is set in **Aeonik** (display + body), with ?px body text. Layout: 1296px container, top-fixed+transparent navigation, 1 sections. Built with astro, google-tag-manager, netlify.

## 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 |
|---|---|---|---|---|---|
| `on-surface` | `#000000` | 0 0 0 | text | 91.2% | `--header-text-color` |
| `background` | `#2B2E3A` | 0.303 0.022 274 | bg | 0.33% | `--color-grey-blue` |
| `white` | `#FFFFFF` | 1 0 0 | other | 8.2% | `--color-white` |
| `dark-white` | `#E4E6EF` | 0.926 0.012 276.1 | other | 0.25% | `--color-dark-white` |

Contrast: text on background 1.55:1.

The site does not change under `prefers-color-scheme: dark`.

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Aeonik** | display, body | 400 | 100.0% | webfont |

Declared in `@font-face` but not used to paint text on this page: IBM Plex Mono, Lusion Mono. Don't treat these as the page's fonts.

Scale (px): 12, 13, 14, 14.5, 18, 36, 43, 48.5, 50.5, 108, 115, 144.  Body ?px at line-height normal; display 144px with tracking -0.02em. Headings are mixed case. On a 390px viewport the body is ?px and display 78px.

## Layout

Spacing has no reliable single base unit; the most used steps are 3.5, 5.5, 9, 10, 11.5, 13, 14.5, 16, 19.5, 22.5, 23, 29, 45, 50px. Content sits in a 1296px container on a 12-column grid. Text density 1.4 (text area / page area).

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

1. **nav** (146px, bg #FFFFFF)

## Elevation & Depth

Style: subtle. Most used shadows:

- `rgba(0, 0, 0, 0.04) 0px 6px 10px 0px, rgba(0, 0, 0, 0.04) 0px 2px 4px 0px`

## Shapes

Dominant corner radius is a full pill; radii in use: 16px, pill. Borders: none.

## Components

- **button-primary**: backgroundColor `#2B2E3A`, textColor `#FFFFFF`, rounded `9999px`, padding `0px 15.8px`, height `44.8px`, fontFamily `Aeonik`, fontSize `14px`, fontWeight `500`
- **button-secondary**: backgroundColor `#E4E6EF`, textColor `#000000`, rounded `9999px`, padding `0px 15.8px`, height `44.8px`, fontFamily `Aeonik`, fontSize `14px`, fontWeight `500`
- **input**: rounded `0px`, height `63px`, padding `11.3px 22.5px`

## Do's and Don'ts

- Do keep the palette monochrome; there is no chromatic brand accent on the page.
- Do set body copy in Aeonik at ?px.
- Do tighten large headlines (-0.02em at 144px).
- Don't introduce font weights beyond 400.
- Do keep corners at pill for most controls.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
