Decoded design system

Stripe's decoded design system: background #FFFFFF, text #000000, accent #533AFD, link #533AFD, primary #061B31; type scale h1 56px / h2 48px / body 16px; 4px spacing base; 0px base radius. The single interactive/action color is #533AFD — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #533AFD — the single interactive color; only on things you click or must notice, never large fills.
• accent, link, button_bg are all #533AFD — one role, not several (the action color).
• accent #533AFD — 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 #061B31 — a brand color — but the call-to-action uses #533AFD, not this.
• secondary #FFE0D1 — 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.

# Stripe — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#061B31` |
| accent | `#533AFD` |
| link | `#533AFD` |
| secondary | `#FFE0D1` |
| button_bg | `#533AFD` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#533AFD` — 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 `#533AFD` — one role, not several (your action color).
- **accent** `#533AFD` — 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** `#061B31` — a brand color — but the call-to-action uses #533AFD, not this.
- **secondary** `#FFE0D1` — 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` 66.5% · `#FE8E6B` 7.9% · `#B3B5DE` 6.4% · `#D48FA7` 6.3%

## Typography

- Heading: **Söhne** _(free fallback: Inter)_
- Body: **Söhne** _(free fallback: Inter)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 56px / 300 · lh 58px · tracking -1.4px |
| h2 | 48px / 300 · lh 48px · tracking -0.96px |
| h3 | 44px / 300 · lh 51px · tracking -0.88px |
| body | 16px / 400 · lh 22px |
| small | 15px / 400 · lh 21px |

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

> **Fonts —** Söhne is proprietary — closest free match: Inter (Google). Load Inter; keep Söhne first so licensed users still get it.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 10px, 11px, 12px, 14px, 16px, 20px — snap all gaps/padding to these
- section rhythm: 96px top/bottom padding per section (measured)

## Radius
- base: 0px
- button: 4px
- card: 4px
- sharp: 1px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#533AFD` / `#FFFFFF` | none | 4px | 15.5px 24px 16.5px 24px | 400 16px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#533AFD` | 1px solid rgb(255, 255, 255) | 4px | 10.5px 20px 13.5px 20px | 400 14px | none |

**States (measured, not guessed)**

- primary hover: background `#4032C8`
- primary focus: outline `3px solid rgba(84, 82, 251, 0.75)`
- secondary hover: border `1px solid rgb(76, 63, 204)` · background `rgba(255, 255, 255, 0.937)` · color `#302C93`
- transition: `background-color 0.3s cubic-bezier(0.25, 1, 0.5, 1)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.1) 0px 2px 5px 0px`
- overlay: `rgba(0, 0, 0, 0.1) 0px 30px 60px -50px, rgba(50, 50, 93, 0.25) 0px 30px 60px -10px`

## Motion
- durations: 300ms (dominant) · 800ms · 150ms
- easings: `cubic-bezier(0.25, 1, 0.5, 1)` (dominant) · `cubic-bezier(0.165, 0.84, 0.44, 1)`
- animated properties: fill, opacity, color, transform

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: `div.book-of-the-week__pictur` @0ms → `div.book-of-the-week__conten` @0ms → `h2.hds-heading` @571ms → `p.hds-text`×4 @571ms → `span.hds-text`×4 @571ms → `a.hds-link` @571ms
- `button.UniversalChatCtaButtonLa` — transform none→rotate(360deg) — 3000ms · loops
- scroll reveal: 19 elements rest at opacity 0, translateY(-65px), animate in over 0.25s linear (5 revealed during the drive).

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

## Components (measured)
- card ×4: pad 40px 0px 40px 0px · r 8px · bg rgba(0, 0, 0, 0)
  - hover: font-weight `400` · letter-spacing `normal`
- link: #7D8BA4 · no underline — hover #061B31

## Responsive (measured)
- breakpoints: 480px · 600px · 640px · 939px · 1264px · 1300px
- mobile (390px): hero 34px · 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.
