Decoded design system

Chord's decoded design system: background #FCFCFC, text #000000, accent #12A594, link #838383, primary #12A594; type scale h1 24px / h2 18px / body 14px; 8px spacing base; 6px base radius. The single interactive/action color is #202020 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #202020 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent are all #12A594 — one role, not several (the action color).
• accent #12A594 — accent for emphasis — keep it rare on the page.
• link #838383 — reads as a neutral UI color, not a link accent — verify against the reference (action = #202020).

# Chord — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FCFCFC` |
| surface | `#ECECEC` |
| border | `#D6D6D6` |
| text | `#000000` |
| text_muted | `#5F5F5F` |
| primary | `#12A594` |
| accent | `#12A594` |
| link | `#838383` |
| button_bg | `#202020` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#202020` — 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` are all `#12A594` — one role, not several.
- **accent** `#12A594` — accent for emphasis — keep it rare on the page.
- **link** `#838383` — reads as a neutral UI color, not a link accent — verify against the reference (action = #202020).
- **Page coverage** (full-page screenshot pixels): `#FCFCFC` 94.6% · `#EBEEEE` 3.1% · `#ADAAAE` 2.3%

## Typography

- Heading: **JetBrains Mono**
- Body: **JetBrains Mono**
- Mono: **JetBrains Mono**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 24px / 700 · lh 24px |
| h2 | 18px / 400 · lh 28px |
| body | 14px / 500 · lh 20px |
| small | 12px / 500 · lh 16px |

- Weight ladder: 400 · 500 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** JetBrains Mono — free, on Google.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 12px, 16px, 20px, 24px, 32px, 48px — snap all gaps/padding to these

## Radius
- base: 6px
- button: 8px
- card: 6px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#202020` / `#FFFFFF` | 1px solid rgb(32, 32, 32) | 8px | 0px 12px 0px 12px | 500 14px | none |
| secondary | `#FFFFFF` / `#202020` | 1px solid rgb(224, 224, 224) | 8px | 0px 12px 0px 12px | 500 14px | none |

**States (measured, not guessed)**

- primary hover: border `1px solid rgb(100, 100, 100)` · background `#646464`
- primary focus: outline `2px solid rgb(83, 185, 171)`
- secondary hover: background `#F0F0F0`
- transition: `background-color 0.15s cubic-bezier(0.23, 1, 0.32, 1)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.02) 2px 2px 4px 0px, rgba(0, 0, 0, 0.03) 0px 1px 2px 0px`

## Motion
- durations: 150ms (dominant) · 1000ms · 200ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `cubic-bezier(0.23, 1, 0.32, 1)`
- animated properties: background-color, 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)

| Token | Value |
|-------|-------|
| `--gray-1` | `#fcfcfc` |
| `--gray-2` | `#f9f9f9` |
| `--gray-3` | `#f0f0f0` |
| `--gray-4` | `#e8e8e8` |
| `--gray-5` | `#e0e0e0` |
| `--gray-6` | `#d9d9d9` |
| `--gray-7` | `#cecece` |
| `--gray-8` | `#bbb` |
| `--gray-9` | `#8d8d8d` |
| `--gray-10` | `#838383` |
| `--gray-11` | `#646464` |
| `--gray-12` | `#202020` |

_…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 1152px

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 0 | 860 | — | — | 0/0 | — |

## Motion choreography (measured)
Load order: `div.animate-pulse`×3 @0ms → `svg.animate-spin`×2 @0ms
- `div.animate-pulse` — opacity 1→1 — 2000ms cubic-bezier(0.4, 0, 0.6, 1) · loops
- `svg.animate-spin` ×2 — transform none→rotate(360deg) — 1000ms · loops

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

## Components (measured)
- input: h 28px · r 8px · border 1px solid rgb(232, 232, 232) · bg #FCFCFC · placeholder #8D8D8D
  - focus ring: `` — this exact construction, don't invent your own
- link: #12A594 · no underline — hover #0D9B8A

## Responsive (measured)
- breakpoints: 768px · 1024px
- mobile (390px): 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.
