Decoded design system

Checkout.com's decoded design system: background #000000, text #272932, accent #186AFF, link #FFFFFF, primary #186AFF; type scale h1 200px / h2 80px / body 16px; 4px spacing base; 10px base radius. The single interactive/action color is #186AFF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #186AFF — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, button_bg are all #186AFF — one role, not several (the action color).
• accent #186AFF — 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.
• link #FFFFFF — reads as a neutral UI color, not a link accent — verify against the reference (action = #186AFF).
• secondary #0C1142 — 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.

## Colors

| Role | Value |
|------|-------|
| bg | `#000000` |
| surface | `#020203` |
| border | `#050607` |
| text | `#272932` |
| text_muted | `#18191F` |
| primary | `#186AFF` |
| accent | `#186AFF` |
| link | `#FFFFFF` |
| secondary | `#0C1142` |
| button_bg | `#186AFF` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#186AFF` — 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`, `button_bg` are all `#186AFF` — one role, not several (your action color).
- **accent** `#186AFF` — 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.
- **link** `#FFFFFF` — reads as a neutral UI color, not a link accent — verify against the reference (action = #186AFF).
- **secondary** `#0C1142` — 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): `#000000` 82.5% · `#FFFFFF` 11.2% · `#B3B7BE` 2.5% · `#344E7D` 1.7%

## Typography

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 200px / 700 · lh 200px |
| h2 | 80px / 700 · lh 72px |
| h3 | 48px / 700 · lh 43px · tracking -1.92px |
| body | 16px / 400 · lh 24px |
| small | 14px / 700 · lh 11px · tracking 1.68px |
| eyebrow | 14px / 700 · tracking 1.68px |

- Weight ladder: 300 · 400 · 500 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 8px, 10px, 12px, 16px, 20px, 24px, 32px, 40px, 64px — snap all gaps/padding to these
- section rhythm: 80px top/bottom padding per section (measured)

## Radius
- base: 10px
- button: 6px
- card: 8px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#186AFF` / `#FFFFFF` | none | 6px | 12px 24px 12px 24px | 500 14px | none |
| secondary | `rgba(255, 255, 255, 0)` / `#FFFFFF` | 1px solid rgb(255, 255, 255) | 6px | 11px 23px 11px 23px | 500 14px | none |

**States (measured, not guessed)**

- primary hover: background `#1B5DD6`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- transition: `background-color 0.3s cubic-bezier(0.23, 1, 0.32, 1)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.2) 0px 0px 18px 0px`

## Motion
- durations: 300ms (dominant) · 200ms · 250ms
- easings: `ease` (dominant) · `cubic-bezier(0.23, 1, 0.32, 1)`
- animated properties: color, background-color, opacity, max-height

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

## 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.
