--- version: alpha name: revolut.com description: "Light product system built on #ffffff with #1f1f1f as the primary CTA accent. Type anchored in Aeonik Pro at 87.5733px / weight 500. Extracted automatically from https://revolut.com/ — rendered styles via getComputedStyle() + CSS custom properties (token-only values may not be painted)." narrative: | revolut.com is built on a pure-white canvas (rgb(255, 255, 255)). The system uses rgb(31, 31, 31) as the singular interactive color. Moderately rounded CTAs (12px) — modern SaaS standard, neither sharp nor pill alongside Aeonik Pro as the primary typeface. Depth comes from borders and surface contrast rather than shadows — a flat, structural elevation model. Interactions are smoothed by transitions across many elements, with little or no keyframe animation. colors: background: "#ffffff" surface-1: "#ffffff" surface-2: "#ffffff" ink: "#1f1f1f" primary: "#1f1f1f" on-primary: "#ffffff" primary-hover: "rgba(55, 108, 213, 0.2)" hairline: "rgba(31, 31, 31, 0.08)" semantic-error: "#a90b1a" semantic-success: "#005f48" semantic-warning: "#774915" typography: display-xl: fontFamily: "Aeonik Pro, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 87.5733px fontWeight: 500 lineHeight: 1 letterSpacing: -2.08px display-md: fontFamily: "Aeonik Pro, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 18px fontWeight: 400 lineHeight: 1.33 letterSpacing: 0 body: fontFamily: "Inter, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 16px fontWeight: 400 lineHeight: normal letterSpacing: 0 caption: fontFamily: "Inter, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 12px fontWeight: 400 lineHeight: 1.5 letterSpacing: 0.18px button: fontFamily: "Aeonik Pro, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 16px fontWeight: 500 lineHeight: 1.38 letterSpacing: 0 rounded: none: 0px xs: 12px sm: 20px md: 22.5px lg: 9999px xl: 10007px pill: 9999px spacing: xxs: 2px xs: 16px sm: 24px md: 30px lg: 40px xl: 48px xxl: 64px components: button-icon-button: backgroundColor: "transparent" textColor: "{colors.hairline}" typography: "{typography.body}" rounded: "{rounded.xs}" button-icon-button-2: backgroundColor: "{colors.hairline}" textColor: "{colors.on-primary}" typography: "{typography.body}" rounded: "{rounded.lg}" padding: 0px 20px button-pill: backgroundColor: "transparent" textColor: "{colors.on-primary}" typography: "{typography.body}" rounded: "{rounded.lg}" padding: 8px 10px tab-ghost-tab: backgroundColor: "transparent" textColor: "{colors.on-primary}" typography: "{typography.body}" rounded: "{rounded.none}" padding: 0px 20px tab-pill-tab: backgroundColor: "{colors.on-primary}" textColor: "#000000" typography: "{typography.body}" rounded: "{rounded.lg}" padding: 10px 26px extracted_at: "2026-06-11T05:02:18.735Z" completeness: 49 scoreVersion: "v2" --- # Design System — revolut.com > Extracted automatically by Prism from https://revolut.com > Date: 2026-06-11 > Viewport: Desktop 1440x900 + Mobile 390x844 > Values are extracted, not hand-written: rendered styles via getComputedStyle() + colors declared in CSS custom properties (token-only values are marked `(token)` and may not be painted). ## 0.

Skip §11–12 unless extending. ## 1. Visual Theme & Atmosphere revolut.com uses a pure-white canvas (`#ffffff`), letting typography, color and imagery carry the visual weight. Headlines are set in **Aeonik Pro**, a sans-serif display face (the dominant type signature, e.g. "Banking & Beyond" at 87.5733px). Body text is set in **Inter**. Negative letter-spacing at display sizes (-2.08px at 87.5733px) compresses headlines into engineered blocks, dense and precise. Body text reads in Near-Black (`#1f1f1f`) — softened from pure black, a small but deliberate detail that lowers reading friction. **Near-Black** (`#1f1f1f`) provides interactive distinction without visual aggression. Shadow is absent by design — depth is conveyed through translucent borders and luminance steps rather than light simulation. Border radius varies from pill-shaped (fully rounded) to moderately rounded elements, creating visual rhythm. Motion design uses smooth easing curves for polished state transitions. **Key Characteristics:** - Background: Pure White (`#ffffff`) - Primary typeface: Inter - Primary text: Near-Black (`#1f1f1f`) - Accent: Near-Black (`#1f1f1f`) - Display: 87.5733px weight 500, letter-spacing -2.08px - Custom fonts loaded: Inter, Aeonik Pro, Aeonik Pro Capitalised ## 2.

These appear on elements not in the sampled set — likely additional display sizes, marketing-section overrides, or third-party-widget styles. ### OpenType & Variable Font Features The typography uses these OpenType features intentionally — this is a sophisticated type system, not a default fallback: - **tabular figures** (`tnum`) — numbers align vertically, essential for pricing tables and dashboards **Clone instruction:** Enable these in your CSS: ```css body { font-feature-settings: "tnum"; } ``` ## 4. Component Stylings ### Buttons **Icon Button** - Background: `transparent` - Text: `rgba(31, 31, 31, 0.8)` `{colors.hairline}` - Padding: 0px - Radius: 12px - Font: 16px weight 400 - Use: Toolbar/UI icons **Icon Button** - Background: `#1f1f1f` `{colors.hairline}` - Text: `#ffffff` `{colors.on-primary}` - Padding: 0px 20px - Radius: 9999px - Font: 16px weight 400 - Use: Toolbar/UI icons **Pill** - Background: `transparent` - Text: `#ffffff` `{colors.on-primary}` - Padding: 8px 10px - Radius: 9999px - Font: 16px weight 500 - Use: Status pills, tags, chips **Ghost** - Background: `transparent` - Text: `#c9c9cd` - Padding: 0px - Radius: 12px - Font: 12px weight 400 - Use: Subtle action, toolbar, nav button **Pill** - Background: `transparent` - Text: `#1f1f1f` `{colors.hairline}` - Padding: 0px - Radius: 12px - Font: 14px weight 400 - Use: Status pills, tags, chips ### Tabs **Ghost Tab** - Background: `transparent` - Text: `#ffffff` `{colors.on-primary}` - Padding: 0px 20px - Radius: 0px - Font: 16px weight 400 - Use: Navigation tabs, filter tabs **Pill Tab** - Background: `#ffffff` `{colors.on-primary}` - Text: `#000000` - Padding: 10px 26px - Radius: 9999px - Font: 16px weight 500 - Use: Navigation tabs, filter tabs ## 4b. Component Behaviors (State Matrix) ### Interaction State Narrative *State transitions extracted via Playwright simulation — exact values in the YAML matrix below.* ```yaml component-behaviors: button: default: bg: "rgba(0, 0, 0, 0)" fg: "rgba(31, 31, 31, 0.8)" link: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(244, 244, 244)" navLink: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(31, 31, 31)" tab: default: bg: "rgb(201, 201, 205)" fg: "rgb(0, 0, 0)" badge: default: bg: "rgba(0, 0, 0, 0)" fg: "rgba(31, 31, 31, 0.8)" footerLink: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(31, 31, 31)" ``` **Agent usage**: Validate generated components against this matrix. If your output's `:hover` state changes properties not listed here, you are off-brand. ## 4c. Component Vocabulary (Closed System) *This brand uses ONLY the following component vocabulary. Introducing new variants without justification breaks the system's tonal coherence.* ### Buttons - **3 shape(s)** in this system: `Icon Button`, `Pill`, `Ghost` - **DO NOT introduce new buttons variants** without justification ### Tabs - **2 shape(s)** in this system: `Ghost Tab`, `Pill Tab` - **DO NOT introduce new tabs variants** without justification ## 5. Layout Principles ### Layout Type **top-nav + content** ### Grid Single column, centered content ### Max Width 100% ### Spacing System Generous spacing — editorial breathing room | Token | Value | |-------|-------| | xxs | 2px | | xs | 16px | | sm | 24px | | md | 30px | | base | 36px | | lg | 40px | | xl | 48px | | 2xl | 60px | | 3xl | 64px | ### Border Radius Scale | Name | Value | Use | |------|-------|-----| | None | 0px | No rounding | | Xs | 12px | Tiny corners (badges, micro elements) | | Sm | 20px | Buttons, inputs, small elements | | Md | 22.5px | Cards, containers | | Lg | 9999px | Large rounded elements, pill segments | | Xl | 10007px | Category strips, featured containers | | Full | 9999px | Pills, avatars, circular elements | ### Shape Language | Component | Border Radius | |-----------|---------------| | Buttons | `12px` | | Tabs | `0px` | | Page Body | `0px` | **Shape Personality**: Moderate Rounding — Medium corners (4–12px). Modern SaaS standard, neither sharp nor pill. **Full Radius Spectrum**: 12px, 20px, 22.5px, full/pill (from `allBorderRadii` scan) ## 5b. Spacing Rhythm Names **Measured section padding**: bands use ~64px internal vertical padding (up to 64px) — **generous**. (Distinct from the gap *between* sections above.) Reproduce this generous vertical breathing room; cramped spacing is the #1 tell of a cheap clone. *Named spacing tokens with explicit use cases. Use these names in YOUR code instead of raw pixels for consistency.* | Name | Value | Use case | |------|-------|----------| | **hero** | `64px` | Top/bottom of full-bleed hero sections | | **section** | `48px` | Between major bands (color change, content shift) | | **subsection** | `40px` | Within a section, between content groups | | **card** | `30px` | Card padding, list-item spacing | | **compact** | `24px` | Form fields, tight clusters, badge padding | | **micro** | `16px` | Icon-text gap, tag inner padding | **Agent rule**: NEVER hardcode raw pixel values for spacing in generated UI. Always reference these named tokens (`spacing-rhythm.section`, etc.). ## 5c. Widget & Structure Library Structural patterns extracted from the page DOM — these are the **blueprints** an agent should follow to reproduce the page architecture (not just CSS values). **4/8 structural patterns detected.** ### Hero Pattern - **Composition:** left-aligned — - **Viewport coverage:** 358px tall (not full-viewport) - **Heading:** "Banking & Beyond" — 88px left-aligned - **Subheading:** "This is your bank, redefined. Get powerful daily banking and global freedom. Sign up for free in a tap." - **CTAs:** 1 (primary: "Download the app") - **Clone instruction:** Reproduce the **left-aligned** layout. Use the heading font-size token at the documented size. Pair the centered text with the hero’s decorative visual (gradient / SVG / hero image — see §9b), not bare text. ### Card Grid Pattern - **Card count:** 4 cards detected - **Columns (desktop):** 4-up grid - **Card dimensions:** 386×610px (aspect 0.63:1) - **Gap:** 0px between cards - **Content:** ✗ no image - **Clone instruction:** Build a 4-column grid (desktop) with cards at ~0.63:1 aspect ratio. Text/icon-only cards (no photography). ### Pricing Table Pattern - **Tier count:** 5 pricing tiers - **Layout:** side-by-side (horizontal comparison) - **Columns (desktop):** 5-up - **Clone instruction:** Build a 5-column side-by-side pricing comparison. ### Footer Pattern - **Columns:** 4 - **Links:** 93 total - **Height:** 1909px - **Includes:** ✗ no newsletter | ✓ social icons | ✓ copyright - **Clone instruction:** Build a 4-column footer with ~23 links per column, social media links, and a copyright line. ## 6. Depth & Elevation | Level | Treatment | Use | |-------|-----------|-----| | Flat (Level 0) | No shadow | Page background, content blocks | **Shadow Philosophy**: Flat design — no shadows used. Borders and spacing define structure. ## 7. Motion & Interaction ### Easing System | CSS Variable | Curve | Semantic Name | |--------------|-------|---------------| | `--rui-easing-toast` | `cubic-bezier(0.175,0.885,0.21,1.65)` | Ease Out — Decelerating | | `--rui-easing-shadow` | `cubic-bezier(0.4,0.3,0.8,0.6)` | Custom Ease — Balanced | | `--rui-easing-default` | `cubic-bezier(0.15,0.5,0.5,1)` | Custom Ease — Balanced | ### Duration Scale | CSS Variable | Value | Tier | |--------------|-------|------| | `--rui-duration-xl` | `900ms` | Cinematic | | `--rui-duration-sm` | `200ms` | Normal | | `--rui-duration-skeleton` | `1500ms` | Cinematic | | `--rui-duration-xs` | `100ms` | Fast | | `--rui-duration-md` | `300ms` | Normal | | `--rui-duration-lg` | `450ms` | Slow | ### Copy-Paste Transition Snippets **Shadow** ```css transition: box-shadow 0.2s cubic-bezier(0.4, 0.3, 0.8, 0.6); ``` **Background** ```css transition: background-color 0.3s cubic-bezier(0.15, 0.5, 0.5, 1), opacity 0.3s cubic-bezier(0.15, 0.5, 0.5, 1); ``` **Background** ```css transition: background-color 0.3s cubic-bezier(0.15, 0.5, 0.5, 1), color 0.3s cubic-bezier(0.15, 0.5, 0.5, 1), opacity 0.3s cubic...; ``` **Background** ```css transition: background-color 0.2s, top 0.2s, opacity 0.3s; ``` ### Motion Fingerprint - **Speed Character**: Cinematic & Slow (median duration: `600ms`) - **Dominant Easing**: custom cubic-bezier curves > This design moves with cinematic & slow timing using custom cubic-bezier curves, creating a UI that feels slow and cinematic. ## 8. Do's and Don'ts ### Do - Use Near-Black (`#1f1f1f`) for text — not pure black, it's warmer and more readable - Use Inter as the primary typeface — it defines the brand personality - Use negative letter-spacing (-2.08px) at display sizes for compressed, editorial headlines - Use full-pill radius (9999px) only for specific elements (avatars, pills, toggles) - Use Near-Black (`#1f1f1f`) as the primary accent — it's the brand's signature interactive color - Use 12px border-radius on buttons — the standard corner rounding for interactive elements - Use a single primary CTA in the hero — the design intentionally avoids choice paralysis - Use a 4-column grid on desktop — density matters for this content type - Place 5 pricing tiers side-by-side on desktop — direct comparison is the value prop - Build a content-dense footer (4 columns, ~93 links) — this site treats the footer as a sitemap, not an afterthought ### Don't - Don't use pure black (`#000000`) for text — the near-black adds warmth - Don't substitute with generic sans-serif or serif — the custom font carries the brand - Don't increase letter-spacing on headings — the type is designed to run tight at scale - Don't apply pill radius on rectangular buttons or cards — it's reserved for specific interactive elements - Don't introduce additional saturated accent colors — the palette is intentionally controlled ## 7b. Enforceable Brand Rules *Structured Do/Don't with reasoning and validation tests. Agents can programmatically verify generated UI.* ```yaml rules: - id: brand-canvas-001 type: do rule: "Always use the page background `rgb(255, 255, 255)` as the base canvas" why: "Every component is designed to composit against this exact tone" test: "document.body.style.backgroundColor === 'rgb(255, 255, 255)'" - id: brand-accent-001 type: do rule: "Reserve `rgb(31, 31, 31)` for primary CTAs and brand-mark signals only" why: "Single chromatic assertion device — overuse dilutes meaning" test: "querySelectorAll('[style*=\"rgb(31, 31, 31)\"]').length <= 3 per fold" - id: brand-depth-001 type: dont rule: "Do NOT introduce drop shadows on cards or sections" why: "Containment is achieved via borders, not elevation — adding shadows breaks the depth contract" test: "getComputedStyle(card).boxShadow === 'none'" ``` ## 9. Responsive Behavior ### Breakpoints | Name | Width | Key Changes | |------|-------|-------------| | Mobile | 400px | Single column, compact spacing | | Mobile Large | 600px | Expanded mobile layout | | Tablet | 839px | Multi-column grids begin | | Desktop | 1199px | Full feature layout | | Ultra-wide | 1600px | Maximum content width | | Ultra-wide | 1920px | Maximum content width | ### Token Diff — Desktop vs Mobile | Element | Property | Desktop | Mobile | |---------|----------|---------|--------| | heading | font-size | `87.5733px` | `48px` | | heading | line-height | `87.5733px` | `48px` | | heading | letter-spacing | `-2.08px` | `normal` | ### Collapsing Strategy - Headlines: 87.5733px → 48px on mobile - Navigation: horizontal links → hamburger menu on mobile - Cards: multi-column → stacked vertical on mobile - Footer: multi-column → stacked single column on mobile ### Touch Targets - Buttons: 0px padding - Navigation: adequate spacing between items - Interactive elements: minimum 44px touch target recommended ### Collapsing Narrative How the structural patterns adapt from desktop to mobile (extracted from both viewport extractions): - **Hero collapses left-aligned → centered** — composition shifts (verify on actual mobile render). - **Card grid: 4-up → 1-up** — cards stack as viewport narrows, becoming a vertical list on mobile. - **Pricing collapses to vertical stack** — desktop comparison becomes scrollable tier-by-tier on mobile. - **Footer columns collapse:** 4 columns (desktop) → 1 column (mobile). ## 7c. Visual Effects & Dynamic Behavior *The live/dynamic layer beyond static CSS — reproduce these, not flat substitutes. This is often what separates a faithful clone from a wireframe.* - **Glassmorphism** — 3 frosted/blur layer(s) (e.g. `blur(16px)`). > **Motion fingerprint**: glassmorphism (3 layers) ## 9b. Visual Tone & Photography **Tone:** Mixed photography + illustration A balanced mix of photographic content and vector graphics. Photos likely carry product/lifestyle context while SVG handles icons, logos, and decorative accents. **Canonical Brand Image (OG):** - https://assets.revolut.com/website/images/img-og-retail.png (1200×630px) *This is the image shown when the site is shared on social media — represents the brand visual essence.* **Hero Image (above-fold dominant visual):** - Aspect: 1.58:1 (landscape (16:9-ish)) - Rendered size: 2230×1408px - *Use this aspect ratio + composition for your clone's hero — mimicking the proportion preserves the visual hierarchy.* **Aspect Ratio Distribution:** - Landscape (1.15–2.3): 10 (50%) - Portrait (<0.87): 3 (15%) - Square (0.87–1.15): 0 (0%) - Ultra-wide (>2.3): 7 (35%) **Media Format Mix:** - PNG: 20 (logos, transparent UI elements, mockups) **Average rendered image size:** 890×547px **Above-fold image count:** 7 / 20 **Decorative Patterns Detected:** - **Glassmorphism** detected (`backdrop-filter: blur`) — layered transparent surfaces with blur, modern OS-like aesthetic **Clone instruction for decorative work:** Glassmorphism is a brand signature — use `backdrop-filter: blur(20px)` on overlapping surfaces. **Imagery Guidance for clones:** - Mix photography and illustration intentionally: photos for product/context, vectors for icons + decorative accents. - Respect the format split — replacing JPGs with illustrations (or vice versa) will shift the brand tone. ## 10. Agent Prompt Guide ### Quick Reference - Background: Pure White (`#ffffff`) - Primary text: Near-Black (`#1f1f1f`) - Accent: Near-Black (`#1f1f1f`) - Border: Translucent Near Black (8%) (`rgba(31, 31, 31, 0.08)`) - Font: Inter - Body: 16px weight 400 ### Example Component Prompts - "Create a hero section on Pure White background (#ffffff). Headline at 87.5733px Inter weight 500, line-height 1, letter-spacing -2.08px, color #1f1f1f." - "Create the primary CTA button: `#1f1f1f` background, `rgba(31, 31, 31, 0.8)` text, 12px border-radius, 12px 24px padding, 700 weight, Inter font." - "Build navigation: sticky on `#ffffff`. Inter 16px weight 400 for links." ### Iteration Guide 1. **Canvas**: Set the light canvas to Pure White (`#ffffff`) — every component is composited against this exact base. 2. **Typography**: All type in Inter, weight range 400–800. Never exceed 800 — heavier weights break the brand's tonal restraint. 3. **Accent**: Near-Black (`#1f1f1f`) is the sole interactive color. On hover → Translucent Royal Blue (20%) (`rgba(55, 108, 213, 0.2)`). Use CSS transitions, not opacity/brightness filters. 4. **Motion**: All transitions use `cubic-bezier(0.4,0.3,0.8,0.6)`. Timing: 100ms for micro-interactions, 450ms for layout changes. Never use linear for UI transitions — preserve the brand's easing personality. 5. **Shape**: CTAs at `12px`. Apply border-radius from the extracted scale only — don't invent intermediate values. 6. **Spacing**: Use the `--ca-space-*` token scale (16px–48px). All padding, margin, and gap values are multiples from this scale — no magic numbers. 7. **Tokens**: Import from §11 CSS Export (`--ca-*` vars). Never hardcode hex values — always reference a token so theming remains consistent. ## 11. CSS Design Tokens Raw Export *Copy-paste ready `:root {}` block — all values extracted directly from the live site.* ```css /* Colors */ :root { --ca-on-primary: #ffffff; --ca-hairline: #1f1f1f; --ca-primary-hover: #376cd5; --ca-semantic-error: #a90b1a; --ca-semantic-success: #005f48; --ca-semantic-warning: #774915; } /* Typography */ :root { --ca-font-primary: "Aeonik Pro", system-ui, sans-serif; --ca-text-display: 87.5733px; --ca-text-body: 16px; --ca-text-caption: 12px; --ca-text-button: 16px; } /* Spacing & Radius */ :root { --ca-space-xxs: 2px; --ca-space-xs: 16px; --ca-space-sm: 24px; --ca-space-md: 30px; --ca-space-base: 36px; --ca-space-lg: 40px; --ca-space-xl: 48px; --ca-space-2xl: 60px; --ca-space-3xl: 64px; --ca-radius-none: 0px; --ca-radius-xs: 12px; --ca-radius-sm: 20px; --ca-radius-md: 22.5px; --ca-radius-lg: 9999px; --ca-radius-xl: 10007px; --ca-radius-full: 9999px; } ``` ## 13.

Match the layout primitive (grid N-col / flex direction / block). ## 14. Copy Library (Real Content from Source) *Actual text content extracted from the live page. Use these strings verbatim when reproducing the site — they carry the brand voice.* ```yaml copy: section-headings: - "Your salary, reimagined" - "Join 75+ million customers worldwide and 13 million in the UK" - "Save with a 5% AER (variable)" - "Your money’s safe space" - "Choose your plan" - "Standard" sub-headings: - "Free" ctas: - "Close" - "France" - "Send" - "Kids & Teens" - "Adventure" - "Wedding" - "United Kingdom" - "Learn more and manage" navigation: - "Personal" - "Business" - "Company" - "Log in" - "Sign up" footer-links: - "Standard Free For the financial basics — everything you need" - "Metal £14.99/month For the global travellers and traders — r" - "FAQ page" - "International Money Transfers" - "International Transfers" - "Lounges" ``` **Agent rule**: reuse these exact strings when generating UI. Do NOT translate or rephrase — brand voice is preserved through the original wording. ## 15. Asset Inventory (Image Roles & Ratios) *Image inventory classified by role and aspect ratio. When reproducing the site, allocate this number of assets per role.* ```yaml assets: hero: count: 1 avg-ratio: 1.80 common-aspect: "~16:9 landscape" thumbnail: count: 2 avg-ratio: 1.00 common-aspect: "~1:1 square" sample-alts: - "FR" - "GB" ``` **Agent rule**: when generating placeholder images, match these counts and aspect ratios. Use neutral placeholder backgrounds for `product` (e.g. `#f5f5f5`), full-color photography hints for `hero` and `editorial`. ## 16. Component HTML Templates *Suggested HTML markup for reproducing the key components — based on what was detected in the source DOM.* ### Button (primary action) ```html ``` _Source pattern detected: padding `0px` · radius `12px` · weight `400`_ **Agent rule**: use these markup skeletons as the structural baseline. Apply tokens from §2-3 for visual styling. ## 17. Content Architecture & Resources (Links by Purpose) *The page's links classified by purpose — the information architecture to reproduce. Categories, featured images, devices and projects are extracted from the rendered DOM, not guessed.* **By purpose:** **nav** 4 · **cta** 2 · **auth** 1 · **docs** 3 · **legal** 5 · **footer** 34 · **other** 11 **Primary actions (conversion path):** - Account access — "Log in" (login/signup) → `https://app.revolut.com/start` - Primary call-to-action — "Sign up" (the conversion path) → `https://get.revolut.com/E528/?af_channel=website_direct&af_dp=revolut%3A%2F%2Fapp&af_sub1=%7B%22conversion_page_url%22%3A%22https%3A%2F%2Fwww.revolut.com%2F%22%2C%22cookie_consent%22%3A%5B%5D%2C%22landing_page_url%22%3A%22https%3A%2F%2Fwww.revolut.com%2F%22%2C%22qr_code%22%3Afalse%2C%22website_client_id%22%3A%2225eb63c4-68b3-461f-a9d2-e311b1179dc8%22%7D&deep_link_sub1=DEEPLINK&deep_link_value=revolut%3A%2F%2Fapp&pid=website` - Primary call-to-action — "Try it out" (the conversion path) → `https://get.revolut.com/E528/?af_channel=website_direct&af_dp=revolut%3A%2F%2Fapp&af_sub1=%7B%22conversion_page_url%22%3A%22https%3A%2F%2Fwww.revolut.com%2F%22%2C%22cookie_consent%22%3A%5B%5D%2C%22landing_page_url%22%3A%22https%3A%2F%2Fwww.revolut.com%2F%22%2C%22qr_code%22%3Afalse%2C%22website_client_id%22%3A%2225eb63c4-68b3-461f-a9d2-e311b1179dc8%22%7D&deep_link_sub1=DEEPLINK&deep_link_value=revolut%3A%2F%2Fapp&pid=website` **Signals:** 2/60 links carry a featured image · dominant link roles: footer-link (40), inline-link (15), navigation (4). --- ## Extraction Completeness: 49/100 (D) | Category | Score | Max | Detail | |----------|-------|-----|--------| | Colors & Palette | 8 | 25 | 6 named colors | | Typography | 13 | 20 | 5 roles defined | | Components | 8 | 20 | 2 specs extracted | | Motion & Interaction | 5 | 15 | No keyframes, easing vars | | CSS Custom Properties | 10 | 10 | 347 vars | | Responsive Breakpoints | 5 | 5 | 6 breakpoints | | Variable Fonts | 0 | 5 | None detected | ## 12. Known Gaps & Confidence Explicit list of what this extraction could NOT capture. Agents should not invent values for these — either skip the feature or use the documented baseline + heuristic fallback. *Auto-detected extraction limitations — understand before building:* - **Licensed web fonts (Inter, Aeonik Pro)** — detected but not downloaded. Substitute with your licensed copy or a close fallback (see Typography section for metrics). - **Sparse component extraction** — fewer than 5 component types detected. Highly dynamic sections (modals, datepickers, carousels) require interaction to render and are not captured in a static pass. | Category | What's missing | Fallback strategy | |----------|----------------|-------------------| | **Keyframe animations** | No @keyframes declarations found (transitions only) | Use CSS transitions for state changes; avoid complex scroll-based animations | | **Form inputs** | No text input fields detected on this page | Use the documented border-radius + accent border on focus; 12-16px padding inside | ### Per-section confidence | Section | Confidence | Reason | |---------|------------|--------| | §1 Visual Theme | High | Body bg extracted via getComputedStyle() | | §2 Colors | High | 347 CSS vars (semantic naming requires ≥20 for high) | | §3 Typography | High | 5 typography roles inferred | | §4 Components | Low | 2 component variants captured | | §7 Motion | Medium | Transitions only | | §8 Do's/Don'ts | High | 15 rules generated; design-decisions.json has evidence per rule | | §9 Responsive | High | 6 breakpoints detected | | §9b Photography | High | 20 images, hero present | ## 11.1 CSS Implementation Guide (CSS Interception Engine v2.15+) *Ready-to-use CSS from Prism's CSS Interception Engine — intercepted directly from the site's CSS files (bypasses CORS).
