# Revolut

Revolut's modern fintech reading — pure black canvas with cobalt-violet #494fdf driving energy + #3a40c4 deeper-press secondary. Glass physics at 0.55 alpha for the modern-banking lift; surface-elevated #16181a per Revolut's documented dark surface ladder. The "modern-banking-app dark" register: hairline-light borders (faint white at 0.12 alpha) signal app-style inset rhythm.

This document describes the **Purple Gradient** atmosphere (`revolut-purple-gradient-dark`) — a dark/glass reading of Revolut produced by the Void Energy design system. Render it live at https://voidenergy.dev/atmospheres/revolut, or boot it in any Void Energy app:

```js
voidEngine.loadExternal('https://voidenergy.dev/atmospheres/revolut/purple-gradient-dark.json');
```

## Overview

Revolut's **Purple Gradient** reading. The mood: translucent surfaces under ambient light; the mode: dark. Headings are set in Manrope; body copy is Manrope.

Two principles govern everything below:

1. **Generous whitespace over dense packing.** Surfaces breathe. When a gap feels tight, go one size up rather than down. Void Energy's spacing scale is intentionally wide (8 → 160px).
2. **Sentence case controls over uppercase shouting.** Buttons, inputs, and labels use natural sentence case with medium weight by default. Uppercase is an intentional, infrequent choice — never applied to metrics, chrome, or dashboard cards by default.

## Colors

The palette is built on three layers:

- **Primary (`#494fdf`)** — the single interactive accent. Used for buttons, links, focused inputs, and selection states. Do not repurpose for decoration.
- **Secondary (`#3a40c4`)** — companion accent for secondary actions, charts, and data-series 2. Always distinguishable from primary; never a competing focal point.
- **Surface stack** — three background layers that convey depth:
  - `surface-container` (`#000000`) — the page canvas.
  - `surface` (`#16181a`) — floating cards, panels, and chrome.
  - `outline` (`#323435`) — borders and dividers. Low-contrast by design: borders should whisper structure, not shout.

Text forms a descending-contrast hierarchy:

- `on-surface` (`#ffffff`) — primary text. WCAG AA against surface layers.
- `on-surface-variant` (`#c9c9cd`) — secondary text, captions, metadata.
- `neutral` (`#8d969e`) — disabled states and tertiary hints only.

Semantic signal:

- `error` (`#ff3c40`) — destructive actions and validation failures. Reserved for genuinely negative states; not for warnings or info.

## Typography

This atmosphere pairs **Manrope** for headings and **Manrope** for body. The full nine-level scale (display through label) is in the frontmatter `typography` block.

### Runtime font loading

The Void Energy runtime self-loads Revolut's typeface family via `new FontFace()` and `document.fonts.add()`. To replicate without the runtime, register the font with your own `@font-face` declaration using:

- **Heading**: `Manrope` — `https://cdn.jsdelivr.net/fontsource/fonts/manrope:vf@latest/latin-wght-normal.woff2` (weight `200 800`)

### Brand typography overrides

Revolut's identity carries explicit overrides on the typographic axis. Anything not listed inherits the system default.

- **Heading weight** (h3, h4): `600`

## Layout & Spacing

Void Energy uses an **8px base grid** with a wide scale:

- **Component level** (tight): xs (8), sm (16), md (24), lg (32)
- **Layout level** (accelerated): xl (48), 2xl (64), 3xl (96), 4xl (128), 5xl (160)

Apply along two axes:

1. **Surface padding floor.** Floating surfaces use `lg` (32px) minimum padding and `lg` inner gaps. Sunk/inset surfaces drop to `md` (24px). Never use `sm` or `xs` on a floating card.
2. **Layout gaps.** Page sections use `2xl` (64px) between them. Content blocks inside a section use `xl` (48px). Grouped controls use `md` (24px). Tight couplings (label → input, icon + text) use `xs` (8px).

The scale density-scales at runtime across five presets: Compact (×0.8), Cozy (×0.9), Standard (×1), Roomy (×1.1), Airy (×1.2). Static snapshots assume Standard.

## Elevation & Depth

This is a **glass-physics** atmosphere. Floating surfaces are translucent (`rgba(22, 24, 26, 0.55)`) with `backdrop-filter: blur(20px)`; the solid fallback is `#16181a`. Borders are translucent (`rgba(255, 255, 255, 0.12)`); the solid fallback is `#323435`. Hover gains a -3px Y translation and 1.02× scale. The glass effect requires a real backdrop to refract — on a static mock, prefer the solid fallback.

## Shapes

Revolut's radii reflect the brand's shape language. The active scale:

- `rounded.sm`: 6px
- `rounded.md`: 10px
- `rounded.lg`: 16px
- `rounded.xl`: 22px
- `rounded.full`: 9999px

## Components

The frontmatter `components` block covers the canonical atoms. Notes on applying them:

### Buttons

- `button-primary` — primary action, anchored on `#494fdf`. One per view.
- `button-secondary` — companion action, on `#3a40c4`.
- `button-tertiary` — quietest button; for cancel, dismiss, tertiary navigation.

### Inputs & Cards

- `input` — surface background, `body-md` typography, 12px padding. Native `<input>` / `<select>` / `<textarea>` with SCSS providing the visual treatment.
- `card` — surface background, generous 32px padding (`lg`). The default container for content groups.

## Do's and Don'ts

**Do:**

- Use `primary` (`#494fdf`) for exactly one action per view.
- Default to sentence case on buttons and labels. Uppercase is a choice, not a default.
- Maintain WCAG AA contrast (4.5:1 for body text, 3:1 for UI components).
- Apply `lg` (32px) padding minimum to cards.
- Wrap native `<button>`, `<input>`, `<select>` rather than rebuilding interaction from `<div>`.

**Don't:**

- Don't substitute canvas with #0a0a0a near-black — Revolut's documented canvas is pure #000000; the brand explicitly forbids near-black approximations.
- Don't substitute primary with #0666EB or pure violet — canonical Revolut primary is cobalt-violet #494fdf.
- Don't drop glass physics — the bg-surface 0.55 alpha is load-bearing for the modern-banking-app feel.
- Don't repurpose `primary` (`#494fdf`) for decoration. It is a load-bearing interaction signal.
- Don't use `error` (`#ff3c40`) for warnings. Error is reserved for destructive and failure states.
- Don't use `neutral` for body text — it is for disabled states and tertiary hints only.

## Responsive Behavior

Void Energy is mobile-first. Breakpoints:

- **mobile** 0px (default)
- **tablet** 768px
- **desktop** 1024px

Spacing, control heights, and typography all density-scale at runtime. Touch targets have a floor: 44px on coarse pointers (mobile/tablet), 36px on fine pointers (desktop).

## Agent Prompt Guide

When asked to build UI "in the Purple Gradient aesthetic," default to:

- **Backgrounds:** `#000000` for the page canvas; `#16181a` for floating cards.
- **Text:** `#ffffff` for primary, `#c9c9cd` for secondary.
- **Accents:** `#494fdf` for the single most important action; `#3a40c4` for companion actions.
- **Radii:** 10px on surfaces and inputs; pill on buttons.
- **Padding:** 32px on cards, 16px on buttons, 12px on inputs.
- **Typography:** Manrope for headings; Manrope for body and labels.

## The Full System

This file describes the **Purple Gradient** atmosphere as a single snapshot. The Void Energy runtime is larger:

- **Revolut variants** — see https://voidenergy.dev/atmospheres/revolut for the full set of atmospheres in this brand (alternate modes, eras, or interpretations).
- **Three physics presets:** glass (translucent + blur), flat (opaque + crisp shadows), retro (CRT phosphor + steps motion). Physics controls blur, border width, motion, and radius behavior — never color.
- **Two color modes:** light and dark. Glass requires dark; flat and retro work with both.
- **Density scaling:** Compact / Cozy / Standard / Roomy / Airy (×0.8 – ×1.2), applied multiplicatively to the spacing scale.
- **Component library:** Svelte 5 components (Runes) with a native-first pattern — wrappers around `<button>`, `<input>`, `<select>`, `<dialog>`, etc.
- **JSON download:** https://voidenergy.dev/atmospheres/revolut/purple-gradient-dark.json is a portable artifact. Boot it in any Void Energy app via `voidEngine.loadExternal()`, or hand it to any tool that consumes the @void-energy/atmosphere-spec format.
