Decoded design system

Polar's decoded design system: background #090909, text #71727A, accent #FFFFFF, link #FFFFFF, primary #FFFFFF; type scale h1 96px / h2 48px / body 20px; 8px spacing base; 0px base radius. The single interactive/action color is #FFFFFF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #FFFFFF — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, link, button_bg are all #FFFFFF — one role, not several (the 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.

# Polar — Design System

> dark, modern, medium, tailwind — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#090909` |
| surface | `#0F0F0F` |
| border | `#181819` |
| text | `#71727A` |
| text_muted | `#494A4F` |
| 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.
- **Page coverage** (full-page screenshot pixels): `#090909` 96.3% · `#909090` 3.7%

## Typography

- Heading: **PP Neue Montreal** _(free fallback: Space Grotesk)_
- Body: **Inter**
- Mono: **GeistMono**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 96px / 400 · lh 96px |
| h2 | 48px / 500 · lh 60px |
| h3 | 30px / 450 · lh 36px · tracking 0.24px |
| body | 20px / 450 · lh 28px · tracking 0.24px |
| small | 16px / 500 · lh 24px · tracking 0.24px |

- Weight ladder: 400 · 450 · 500 · 550 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** PP Neue Montreal is proprietary — closest free match: Space Grotesk (Google). Load Space Grotesk; keep PP Neue Montreal first so licensed users still get it. Inter — free, on Google.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 8px, 12px, 16px, 20px, 24px, 32px, 48px, 64px, 96px — snap all gaps/padding to these

## Radius
- base: 0px
- button: 3.35544e+07px
- card: 8px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFFFFF` / `#000000` | none | 3.35544e+07px | 12px 20px 12px 20px | 550 14px / 0.14px | none |
| secondary | `#1D1E20` / `#FFFFFF` | none | 9999px | — | — | none |

**States (measured, not guessed)**

- transition: `opacity 0.1s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 200ms (dominant) · 150ms · 100ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant)
- animated properties: fill, color, background-color, border-color

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

_…and 108 more measured on the page._

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- container max 1280px

## Motion choreography (measured)
- overlay dialog (auto-opened): panel #101011 · r 7.6px · border 1px solid rgb(32, 32, 34) · shadow 
  - exit: transform+opacity from none,1 · 150ms linear

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Responsive (measured)
- breakpoints: 640px · 768px · 1024px · 1280px · 1536px
- mobile (390px): hero 60px · body 16px · nav: inline

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
