Decoded design system

Nubank Mobile's decoded design system: background #FFFFFF, text #000000, accent #17C242, link #FFFFFF, primary #17C242; type scale h1 112px / h2 72px / body 16px; 8px spacing base; 12px base radius. The single interactive/action color is #8D0DE3 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #8D0DE3 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent are all #17C242 — one role, not several (the action color).
• accent #17C242 — accent for emphasis — keep it rare on the page.
• link #FFFFFF — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).

# Nubank Mobile — Design System

> light, consumer, high — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#17C242` |
| accent | `#17C242` |
| link | `#FFFFFF` |
| button_bg | `#8D0DE3` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#8D0DE3` — 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` are all `#17C242` — one role, not several.
- **accent** `#17C242` — accent for emphasis — keep it rare on the page.
- **link** `#FFFFFF` — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **Page coverage** (full-page screenshot pixels): `#D3C6BB` 14.1% · `#09020B` 13.8% · `#2A2516` 13.3% · `#635632` 12.9%

## Typography

- Heading: **nuSansDisplay** _(free fallback: Newsreader)_
- Body: **nuSansText** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 112px / 600 · lh 105px · tracking -1.4px |
| h2 | 72px / 600 · lh 68px · tracking -1.2px |
| h3 | 34px / 600 · lh 32px · tracking -0.7px |
| body | 16px / 600 · lh 19px |

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

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

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 6px, 8px, 16px, 20px, 24px, 28px, 32px, 40px, 48px, 56px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 9999px
- card: 12px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#8D0DE3` / `#FFFFFF` | 1px solid rgba(255, 255, 255, 0) | 9999px | 0px 24px 0px 24px | 600 16px | none |

**States (measured, not guessed)**

- primary hover: background `#5D0599`
- primary focus: border `1px solid rgb(141, 13, 227)` · outline `2px solid rgb(141, 13, 227)`

## Motion
- durations: 1600ms (dominant) · 150ms · 2500ms
- easings: `ease-in-out` (dominant) · `ease-out`
- animated properties: opacity

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

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- container max 1260px · common grid: 12-col
- nav: 64px fixed

| Section (y) | Height | Cols | Gap | Pad y | Split |

## Motion choreography (measured)
Load order: `div.css-12tw2yb` @0ms → `div.css-ehsg9o` @0ms → `circle.css-1jpki61` @0ms → `div.css-l17lnj`×2 @401ms → `div.css-1hht2g1` @401ms → `div.css-8au1kw` @401ms
- `header.css-1c1mct4` — opacity 0→1 · transform translateY(-20px)→translateY(0px) — 600ms cubic-bezier(0.22, 1, 0.36, 1) (delay 150ms)
- `div.css-l17lnj` ×2 — transform translateY(-3px)→translateY(-3px) — 2500ms ease-in-out · loops
- scroll reveal: 3 elements rest at opacity 0, animate in over 1.6s ease-in-out (1 revealed during the drive).

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

## Components (measured)
- link: #8D0DE3 · no underline — hover #5D0599

## Responsive (measured)
- mobile (390px): hero 48px · 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.
