Decoded design system

Muse's decoded design system: background #F9F7F4, text #000000, accent #F6953C, link #803EDE, primary #422B59; type scale h1 78px / h2 56px / body 21px; 4px spacing base; 6px base radius. The single interactive/action color is #F6953C — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #F6953C — the single interactive color; only on things you click or must notice, never large fills.
• accent, secondary, button_bg are all #F6953C — one role, not several (the action color).
• accent #F6953C — 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.
• primary #422B59 — a brand color — but the call-to-action uses #F6953C, not this.
• link #803EDE — inline text links and link-styled controls.

# Muse — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#F9F7F4` |
| surface | `#EAE8E5` |
| border | `#D3D1CF` |
| text | `#000000` |
| text_muted | `#5E5D5C` |
| primary | `#422B59` |
| accent | `#F6953C` |
| link | `#803EDE` |
| secondary | `#F6953C` |
| button_bg | `#F6953C` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#F6953C` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `secondary`, `button_bg` are all `#F6953C` — one role, not several (your action color).
- **accent** `#F6953C` — 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.
- **primary** `#422B59` — a brand color — but the call-to-action uses #F6953C, not this.
- **link** `#803EDE` — inline text links and link-styled controls.
- **Page coverage** (full-page screenshot pixels): `#F9F7F4` 50.6% · `#ECE8E2` 41.5% · `#ADB0B2` 7.8%

## Typography

- Heading: **Marat Sans** _(free fallback: Newsreader)_
- Body: **Marat Sans** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 78px / 500 · lh 85px |
| h2 | 56px / 500 · lh 56px |
| h3 | 43px / 600 · lh 43px · tracking -0.8px |
| body | 21px / 400 · lh 25px |
| small | 19px / 400 · lh 23px |

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

> **Fonts —** Marat Sans may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 6px, 10px, 12px, 14px, 16px, 20px, 22px, 24px, 29px, 30px — snap all gaps/padding to these
- section rhythm: 43px top/bottom padding per section (measured)

## Radius
- base: 6px
- button: 6px
- card: 13px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#F6953C` / `#FFFFFF` | none | 6px | 12px 16px 12px 16px | 400 20.976px | rgba(0, 0, 0, 0.1) 0px 0px 4px 0px |
| secondary | `rgba(0, 0, 0, 0)` / `rgba(0, 0, 0, 0.7)` | none | 0px | 0px 0px 0px 0px | 400 20.976px | none |

**States (measured, not guessed)**

- primary hover: box-shadow `rgba(0, 0, 0, 0.2) 0px 2px 10px 0px`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: color `#803EDE`

## Shadows (elevation)
- subtle: `rgba(39, 38, 36, 0.1) 0px 0px 4px 0px`
- card: `rgba(39, 38, 36, 0.1) 0px 4px 12px 0px`
- button: `rgba(0, 0, 0, 0.1) 0px 0px 4px 0px`
- overlay: `rgba(0, 0, 0, 0.15) 0px 4px 20px 0px`

## Motion
- durations: 200ms (dominant) · 300ms · 500ms
- easings: `ease` (dominant) · `ease-out`
- animated properties: opacity, color, width, transform

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 1200px · common grid: 2-col
- nav: 73px · backdrop blur(7px) · bg rgba(255, 255, 255, 0.9)

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 0 | 720 | 2 | 29 | 0/0 | — |

## Components (measured)
- input: h 49px · r 6px · bg #FFFFFF · placeholder #757575
  - focus ring: `1px auto rgb(16, 16, 16)` — this exact construction, don't invent your own
- link: #FFFFFF · underline

## Themes (both measured)
- dark counterpart: bg `#343434` · text `#FFFFFF`
- tokens that flip between modes:
  - `--lm-text-bright`: `#000000` → `#000000`

## Responsive (measured)
- breakpoints: 450px · 600px · 850px
- mobile (390px): hero 33px · body 19px · 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.
