# Iana Design System

## Overview

The interface is light, built on **White (#FFFFFF)** with **Warm Slate (#56564F)** text, and **Blue (#2E7DCA)** as the main accent.

Type is set in **Noto**. Headlines run large; body text is 16px. The surface language is flat. Corners are mostly 3px.

Measured from [iana.org](https://www.iana.org/) on October 24, 2026 at 1440×900 and 390×844 from 76 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 6 roles.

- **White (#FFFFFF):** Page background, seen 3 times. Token `background`, CSS `--color-white`.
- **Warm Slate (#56564F):** Primary text and headings, seen 3 times. Token `on-surface`, CSS `--color-text`.
- **Cool Gray (#9999A0):** Secondary text, seen 23 times. Token `on-surface-variant`, CSS `--color-footer-text`.
- **Cool Mist (#EBEFF1):** Raised areas one step from the page, seen 2 times. Token `surface-container-low`, CSS `--color-chrome`.
- **Blue (#2E7DCA):** Most used accent color, seen 14 times. Token `primary`.
- **Near Black (#000000):** Text and icons on primary. Token `on-primary`.

## Typography

**Noto** carries the whole interface. Fallback stack: `Noto, sans-serif`.

- **headline-display:** Noto 29px at weight 500 (22.5px on mobile). Page title (h1).
- **body-md:** Noto 16px at weight 400. Body text.
- **body-lg:** Noto 18px at weight 500. Lead paragraphs.
- **body-sm:** Noto 12px at weight 400. Secondary and small text.
- **label-md:** Noto 12px at weight 700. Buttons, navigation and labels.

## Layout

Spacing does not follow a strict grid: 25% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** sm 5px, md 10px, lg 32px.
- **Page margin:** 20px on each side of full-width sections.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from tonal surface steps (#EBEFF1).

## Shapes

Most elements use 3px corners. Measured radii, most used first:

- **md (3px):** 4 elements.

## Components

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

- **input-field (“search”):** #FFFFFF fill, #444746 text, 16px/400, 3px radius, padding 0px.
- **link:** transparent fill, #9999A0 text, padding 0px.

## Do's and Don'ts

- Do use #FFFFFF for the page and lift surfaces in small steps: #EBEFF1.
- Do keep text in 2 levels: #56564F, #9999A0.
- Do reserve #2E7DCA for primary actions and key highlights.
- Do reuse the measured spacing steps (5px, 10px, 32px).
- Do use 3px corners on most elements.
- Don't use #9999A0 for body text; it reaches 2.8:1 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 Noto.
- Don't use #2E7DCA for large backgrounds or body text.
- Don't make interface transitions slower than 0.2s.

## Motion

Interface transitions are quick: 0.2s.

- **Easing:** `linear`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
