## Overview

An immersive, retro-futuristic cockpit experience designed to showcase the GT Planar typeface.

- **Background (`#000000`)** — uses `bg` token
- **Primary text (`#ffffff`)** — uses `ink` token

- **Muted (`#949494`)** — uses `muted` token
- **Borders (`rgba(255, 255, 255, 1.0)`)** — uses `line` token

## Typography

- **Display:** geometric-sans
- **Body:** geometric-sans
- **Mono:** monospaced

- Use uppercase text for all UI labels and navigation elements.
- Maintain a tight line height of 1.0 for all large display type.
- Utilize the Tabular variant of the font for any numerical data displays.
- Set base font weight to 300 for a refined, technical feel.

## Layout

A full-viewport cockpit frame with fixed corner panels and a central focus area.

*Rhythm:* Based on a 4px grid, using specific padding like 5px and 10px for UI panels.

## Elevation & Depth

- 1px 0px 0px 0px #ffffff
- 0px 1px 0px 0px #ffffff
- 1px 1px 0px 0px #ffffff

## Shapes

- `sm`: 0px
- `md`: 0px
- `lg`: 0px
- `pill`: 9999px

## Components

- **button:** Minimalist, bordered buttons with uppercase text, often using a solid accent background like the red 'EXIT' box.
- **card:** Complex, data-dense UI panels with 1px borders and technical labels.
- **chip:** Simple rectangular containers for status indicators (e.g., ON/OFF).
- **input:** Standard text inputs not prominently featured.
- **hero:** A massive, centered typographic display framed by cockpit UI elements.

## Do's and Don'ts

**Don't:**
- Don't use rounded corners — the screenshot shows sharp, zero-radius corners on all panels and buttons.
- Don't use soft shadows — the screenshot shows sharp, 1px solid borders acting as structural elements.
- Don't use a bright, multi-color palette — the screenshot shows a strict black, white, and green scheme with minimal red.
- Don't use mixed-case UI labels — the screenshot shows consistent use of uppercase text for all technical labels.
- Don't use decorative sans-serifs — the screenshot shows a highly geometric, technical display font for headings.
- Don't use large padding — the screenshot shows dense, compact UI panels with minimal internal padding.

## System Prompt (paste into AI agent)

```
This design is a highly stylized, retro-futuristic space cockpit interface created to showcase the GT Planar typeface. It features a stark, high-contrast palette of pure black (#000000), white (#ffffff), and a vibrant technical green (#00ff85), with a single red (#ff0000) accent for critical actions. The typography relies exclusively on geometric sans-serif categories, utilizing the GT Planar font family at both extreme display sizes and small technical scales. Critical donts include: avoid using rounded corners or soft shadows, as the interface is defined by sharp 1px borders; do not use mixed-case text for UI elements, which are strictly uppercase; and avoid any decorative or friendly aesthetic, maintaining a purely technical, mechanical feel throughout.
