Polar does payments infrastructure as gallery minimalism: PP Neue Montreal at 96px/400 in white on near-black, 64px stat numerals, zero-radius surfaces, and line-art diagrams of billing primitives. The monochrome austerity is the pitch — open-source Merchant of Record tooling that looks like it was designed by the same hand that ships the API.

# Polar — Design System

> dark, modern, medium, tailwind

Polar does payments infrastructure as gallery minimalism: PP Neue Montreal at 96px/400 in white on near-black, 64px stat numerals, zero-radius surfaces, and line-art diagrams of billing primitives. The monochrome austerity is the pitch — open-source Merchant of Record tooling that looks like it was designed by the same hand that ships the API.

## Colors

| Role | Value |
|------|-------|
| bg | `#090909` |
| surface | `#171717` |
| border | `#2D2D2D` |
| text | `#FFFFFF` |
| text_muted | `#A1A1A1` |
| primary | `#FFFFFF` |
| accent | `#FFFFFF` |
| link | `#FFFFFF` |
| button_bg | `#FFFFFF` |
| button_text | `#000000` |

**Using these colors**

- **Action color** `#FFFFFF` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent`, `link`, `button_bg` are all `#FFFFFF` — one role, not several (your action color).
- **accent** `#FFFFFF` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.

## Typography

- Heading: **PP Neue Montreal** _(free fallback: Space Grotesk)_
- Body: **Inter**
- Mono: **GeistMono**
- h1: 96px
- h2: 48px
- body: 14px
