Decoded design system

Modern Treasury's decoded design system: background #FFFFFF, text #000000, accent #BAE0CF, link #BAE0CF, primary #543B4E; type scale h1 71px / h2 47px / body 16px; 8px spacing base; 2px base radius. The single interactive/action color is #BAE0CF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #BAE0CF — the single interactive color; only on things you click or must notice, never large fills.
• accent, link, button_bg are all #BAE0CF — one role, not several (the action color).
• accent #BAE0CF — 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 #543B4E — a brand color — but the call-to-action uses #BAE0CF, not this.
• secondary #0C221D — 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.

# Modern Treasury — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#543B4E` |
| accent | `#BAE0CF` |
| link | `#BAE0CF` |
| secondary | `#0C221D` |
| button_bg | `#BAE0CF` |
| button_text | `#151515` |

**Using these colors**

- **Action color** `#BAE0CF` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `link`, `button_bg` are all `#BAE0CF` — one role, not several (your action color).
- **accent** `#BAE0CF` — 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** `#543B4E` — a brand color — but the call-to-action uses #BAE0CF, not this.
- **secondary** `#0C221D` — 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): `#FFFFFF` 93.3% · `#D0D1D0` 2.5% · `#666867` 2.4% · `#EFEEEE` 1.8%

## Typography

- Heading: **mt-neue-text** _(free fallback: Newsreader)_
- Body: **mt-sans** _(free fallback: Newsreader)_
- Mono: **mt-mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 71px / 450 · lh 78px |
| h2 | 47px / 450 · lh 59px |
| h3 | 32px / 400 · lh 40px |
| body | 16px / 360 · lh 24px |
| small | 14px / 330 · lh 21px |

- Weight ladder: 330 · 360 · 400 · 500 · 600 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** mt-neue-text may be proprietary — safe free fallback: Newsreader (Google Fonts). mt-sans may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 9px, 12px, 14px, 16px, 20px, 24px, 32px — snap all gaps/padding to these
- section rhythm: 60px top/bottom padding per section (measured)

## Radius
- base: 2px
- button: 2px
- card: 4px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(0, 0, 0, 0)` / `#151515` | none | 2px | 6px 12px 6px 12px | 600 14px | rgb(21, 21, 21) 0px 0px 0px 1px inset |
| secondary | `#151515` / `#FFFFFF` | none | 2px | 6px 12px 6px 12px | 600 14px | rgb(21, 21, 21) 0px 0px 0px 1px inset |

**States (measured, not guessed)**

- transition: `color 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 150ms (dominant) · 200ms
- 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.

## Motion choreography (measured)
Load order: `button`×2 @0ms

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

## Components (measured)
- input: h 40px · r 0px · bg #FFFFFF · placeholder #151515
- card ×4: pad 24px 24px 24px 24px · r 8px · bg #F8F5F4
  - hover: font-weight `400` · letter-spacing `normal`
- link: rgba(21, 21, 21, 0.8) · underline

## Responsive (measured)
- breakpoints: 375px · 512px · 576px · 600px · 672px · 768px
- mobile (390px): hero 47px · 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.
