Decoded design system

Chroma's decoded design system: background #FAFAF9, text #0A0A0A, accent #171717, link #4A5565, primary #364153; type scale h1 24px / h2 18px / body 14px; 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.
• accent #171717 — accent for emphasis — keep it rare on the page.
• primary #364153 — a brand color — but the call-to-action uses #FFFFFF, not this.
• link #4A5565 — inline text links and link-styled controls.
• secondary #101828 — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.

# Chroma — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FAFAF9` |
| surface | `#EBEBEA` |
| border | `#D6D6D5` |
| text | `#0A0A0A` |
| text_muted | `#656564` |
| primary | `#364153` |
| accent | `#171717` |
| link | `#4A5565` |
| secondary | `#101828` |
| button_bg | `#FFFFFF` |
| button_text | `#FAFAFA` |

**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.
- **accent** `#171717` — accent for emphasis — keep it rare on the page.
- **primary** `#364153` — a brand color — but the call-to-action uses #FFFFFF, not this.
- **link** `#4A5565` — inline text links and link-styled controls.
- **secondary** `#101828` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#FAFAF9` 86.5% · `#313130` 5.6% · `#9F9A94` 5.4% · `#DCDAD6` 2.5%

## Typography

- Heading: **Inter**
- Body: **Inter**
- Mono: **IBM Plex Mono**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 24px / 400 · lh 32px |
| h2 | 18px / 400 · lh 28px |
| body | 14px / 500 · lh 20px |
| small | 12px / 400 · lh 16px |

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

> **Fonts —** Inter — free, on Google.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 10px, 12px, 16px, 20px, 24px, 32px, 48px — snap all gaps/padding to these

## Radius
- base: 0px
- button: 3.35544e+07px
- card: 6px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFFFFF` / `lab(27.1134 -0.956401 -12.3224)` | 1px solid lab(85.1236 -0.612259 -3.7138) | 3.35544e+07px | 10px 16px 10px 16px | 400 14px | none |
| secondary | `lab(7.78201 -0.0000149012 0)` / `lab(98.26 0 0)` | 1px solid rgba(0, 0, 0, 0) | 6px | 0px 10px 0px 10px | 500 14px | none |

**States (measured, not guessed)**

- primary hover: background `lab(98.2596 -0.247031 -0.706708)`
- primary focus: outline `1px auto oklab(0.707999 -0.00000712276 0.0000166297 / 0.5)`
- secondary hover: background `oklab(0.205 -0.00000207871 0.00000478327 / 0.9)`
- transition: `all 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- card: `rgb(240, 240, 240) 6px 6px 0px 0px`

## Motion
- durations: 150ms (dominant) · 300ms · 1500ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease`
- 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.

_…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 · common grid: 3-col
- nav: 68px

## Motion choreography (measured)
Load order: `span.blink-plane`×2 @0ms → `span.flow-line`×3 @0ms → `span.flow-dots`×2 @0ms
- `span.blink-plane` ×2 — opacity 1→1 — 2500ms ease-in-out · loops
- `span.flow-line` ×3 — opacity 0.2→0.2 — 2000ms ease-in-out · loops
- `span.flow-dots` ×2 — opacity 0.3→0.3 — 1500ms ease-in-out · loops
- stagger: `span` ×3 — 665ms apart
- overlay dialog (auto-opened): panel lab(100 0 0) · r 14px · shadow 

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

## Components (measured)
- link: lab(2.75381 0 0) · underline
- disabled: bg #2D333A · text #FFFFFF

## Responsive (measured)
- breakpoints: 640px · 768px · 1024px · 1280px
- mobile (390px): hero 24px · 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.
