# Airform Design System

## Overview

Airform describes itself as: “Airform One moves heat with water. No refrigerants between devices. Architectural design, silent operation, installed in an afternoon.” The interface is light, built on **White (#FFFFFF)** with **Graphite (#454545)** text and almost no color: actions are carried by contrast, not hue.

Type is set in **Oakes Grotesk**. Headlines run large; body text is 16px. The surface language is flat. Controls are pill-shaped.

Measured from [airform.space](https://airform.space/) on October 23, 2026 at 1440×900 and 390×844 from 141 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 10 roles, plus gradient stops #65819C.

- **White (#FFFFFF):** Page background, seen 4 times. Token `background`.
- **Graphite (#454545):** Primary text and headings, seen 7 times. Token `on-surface`, CSS `--color-text`.
- **Slate (#636363):** Secondary text, seen 2 times. Token `on-surface-variant`, CSS `--color-muted`.
- **Snow (#F5F5F7):** Raised areas one step from the page, seen 1 time. Token `surface-container-low`.
- **Snow (#F3F3F6):** Cards and panels, seen 3 times. Token `surface-container`.
- **White 6% (#FFFFFF0F):** Translucent fill for cards and controls, seen 1 time. Token `overlay`.
- **Silver (#DEDEDE):** Borders and dividers, seen 2 times. Token `outline`, CSS `--color-light-line`.
- **White 22% (#FFFFFF38):** Secondary dividers, seen 1 time. Token `outline-variant`.
- **Graphite (#454545):** Primary buttons and calls to action, seen 13 times. Token `primary`, CSS `--color-text`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.

## Typography

**Oakes Grotesk** carries the whole interface. Fallback stack: `Oakes Grotesk, system-ui, sans-serif`.

- **headline-display:** Oakes Grotesk 259px at weight 500, line height 1 (64px on mobile). Page title (h1).
- **headline-lg:** Oakes Grotesk 56px at weight 400, line height 1.1, tracking -0.01em (32px on mobile). Section headings (h2).
- **headline-md:** Oakes Grotesk 40px at weight 300, line height 1.22. Sub-section headings.
- **body-md:** Oakes Grotesk 16px at weight 400. Body text.
- **body-lg:** Oakes Grotesk 22px at weight 300, line height 1. Lead paragraphs.
- **body-sm:** Oakes Grotesk 15px at weight 400, line height 1.4. Secondary and small text.
- **caption:** Oakes Grotesk 12px at weight 400. Captions and fine print.
- **label-lg:** Oakes Grotesk 15px at weight 500, line height 1.33. Large buttons and tabs.
- **label-md:** Oakes Grotesk 14px at weight 400. Buttons, navigation and labels.
- **label-sm:** Oakes Grotesk 13px at weight 500. Small labels and badges.

## Layout

Spacing does not follow a strict grid: 24% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 4px, sm 6.84px, md 9px, lg 18px, xl 49.97px.
- **Sections:** 180px vertical padding between major sections.
- **Gaps:** 49.97px is the most common gap in flex and grid layouts.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from tonal surface steps (#F5F5F7 → #F3F3F6) and #DEDEDE borders.

## Shapes

Interactive controls are pill-shaped. Measured radii, most used first:

- **full (9999px):** 20 elements.
- **md (100px):** 8 elements.
- **sm (16px):** 4 elements.

## Components

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

- **button-primary (“Order”):** #454545 fill, #FFFFFF text, 12px/400, 100px radius, padding 9px 20px.
- **button-ghost (“EN”):** transparent fill, #454545 text, 12px/500, padding 2px.
- **input-field (“Email address”):** #FFFFFF0F fill, #F5F5F7 text, 13.5px/400, 999px radius, padding 9px 14px, border 1px solid #FFFFFF38.

## Do's and Don'ts

- Do use #FFFFFF for the page and lift surfaces in small steps: #F5F5F7, #F3F3F6.
- Do keep text in 2 levels: #454545, #636363.
- Do let contrast carry emphasis; primary actions use #454545 on #FFFFFF.
- Do reuse the measured spacing steps (6.84px, 9px, 18px).
- Do make buttons and chips fully rounded (9999px); most other elements use 100px corners.
- Don't add drop shadows for depth; use tonal surfaces.
- Don't introduce new font families beyond Oakes Grotesk.
- Don't add saturated accent colors; the measured palette is almost entirely neutral.
- Don't make interface transitions slower than 0.35s.

## Motion

Interface transitions are quick: 0.3s, 0.2s, 0.25s, 0.35s.

- **Easing:** `ease`, `cubic-bezier(0.4, 0, 0.2, 1)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
