Decoded design system

Plane's decoded design system: background #F7F7F8, text #000000, accent #006399, link #006399, primary #006399; type scale h1 58px / h2 44px / body 14px; 8px spacing base; 8px base radius. The single interactive/action color is #090B0C — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #090B0C — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, link are all #006399 — one role, not several (the action color).
• accent #006399 — accent for emphasis — keep it rare on the page.

# Plane — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#F7F7F8` |
| surface | `#E8E8E9` |
| border | `#D1D1D2` |
| text | `#000000` |
| text_muted | `#5D5D5E` |
| primary | `#006399` |
| accent | `#006399` |
| link | `#006399` |
| button_bg | `#090B0C` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#090B0C` — 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` are all `#006399` — one role, not several.
- **accent** `#006399` — accent for emphasis — keep it rare on the page.
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 83.2% · `#8EB0C1` 4.6% · `#131D22` 3.6% · `#E7E9EA` 3.6%

## Typography

- Heading: **Satoshi**
- Body: **Inter**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 58px / 430 · lh 75px · tracking -1.74px |
| h2 | 44px / 430 · lh 57px · tracking -1.32px |
| h3 | 24px / 430 · lh 36px |
| body | 14px / 430 · lh 21px |
| small | 13px / 500 · lh 20px |

- Weight ladder: 400 · 430 · 500 · 570 · 600 — use these exact measured weights, not the 400/600 defaults.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 12px, 16px, 20px, 24px, 28px, 32px — snap all gaps/padding to these
- section rhythm: 80px top/bottom padding per section (measured)

## Radius
- base: 8px
- button: 8px
- card: 8px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `lab(2.88725 -0.35163 -0.52478)` / `lab(100 0 0)` | none | 8px | 6px 12px 6px 12px | 500 14px | none |
| secondary | `lab(100 0 0)` / `#000000` | 1px solid lab(94.7027 -0.211328 -0.296319) | 6px | 8px 12px 8px 12px | 600 14px | none |

**States (measured, not guessed)**

- primary hover: background `lab(11.5955 -0.604004 -0.857303)`
- primary focus: background `lab(34.7974 -1.3694 -1.94997)`
- secondary hover: border `1px solid lab(92.9178 -0.295669 -0.414813)` · background `lab(98.238 -0.0635386 -0.0888944)`
- transition: `color 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 150ms (dominant) · 300ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant)
- animated properties: color, background-color, border-color, outline-color

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

## Their own tokens (verbatim from :root)

_…and 108 more measured on the page._

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

## Motion choreography (measured)
- scroll reveal: 2 elements rest at opacity 0, animate in over 0.3s cubic-bezier(0.4, 0, 0.2, 1) (0 revealed during the drive).

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 36px · body 16px · nav: hamburger

## 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.
