--- version: alpha name: jitter.video description: "Light product system built on #ffffff with #ffffff as the primary CTA accent. Type anchored in TWK Lausanne at 80px / weight 800. Extracted automatically from https://jitter.video/ — rendered styles via getComputedStyle() + CSS custom properties (token-only values may not be painted)." narrative: | jitter.video is built on a pure-white canvas (rgb(255, 255, 255)). The system uses rgb(255, 255, 255) as the singular interactive color. Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside TWK Lausanne as the primary typeface. A layered elevation system (9 distinct shadows) building a clear front-to-back hierarchy. Motion is a first-class concern — 94 keyframe animations plus transition-driven interactions. colors: background: "#ffffff" surface-1: "#f2f1f3" surface-2: "#fafafb" ink: "#19171c" ink-muted: "rgba(25, 23, 28, 0.65)" ink-subtle: "#6e6e73" primary: "#ffffff" on-primary: "#111111" primary-hover: "#a981ff" hairline: "#c3c3c6" primary-focus: "#101010" typography: display-xl: fontFamily: "TWK Lausanne, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 80px fontWeight: 800 lineHeight: 0.9 letterSpacing: -2.4px display-md: fontFamily: "TWK Lausanne, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 21px fontWeight: 800 lineHeight: 0.95 letterSpacing: -0.42px body: fontFamily: "Inter, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 12px fontWeight: 400 lineHeight: 1.4 letterSpacing: 0 body-sm: fontFamily: "Inter, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 16px fontWeight: 600 lineHeight: 1.5 letterSpacing: -0.352px caption: fontFamily: "Inter, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 15px fontWeight: 400 lineHeight: 1.2 letterSpacing: -0.32px button: fontFamily: "TWK Lausanne, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 20px fontWeight: 600 lineHeight: 1.38 letterSpacing: -0.4px mono: fontFamily: "Inter, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 17px fontWeight: 600 lineHeight: 1.41 letterSpacing: -0.75px rounded: none: 0px xs: 18px sm: 20px md: 26px lg: 40px xl: 50px pill: 9999px spacing: xxs: 2px xs: 5px sm: 13px md: 24px lg: 37px xl: 40px xxl: 70px components: button-ghost: backgroundColor: "transparent" textColor: "{colors.ink-muted}" typography: "{typography.mono}" rounded: "{rounded.none}" padding: 10px input-text-input: backgroundColor: "#2d2933" textColor: "{colors.primary}" typography: "{typography.mono}" rounded: "{rounded.none}" padding: 13px 210px 13px 24px status-badge-neutral-dark: backgroundColor: "transparent" textColor: "{colors.ink-muted}" typography: "{typography.caption}" rounded: "{rounded.lg}" padding: 7px 20px status-badge-neutral-dark-2: backgroundColor: "transparent" textColor: "#17082c" typography: "{typography.button}" rounded: "{rounded.lg}" padding: 5px 20px alert-alert-banner: backgroundColor: "transparent" textColor: "#ff0000" typography: "{typography.body-sm}" rounded: "{rounded.none}" padding: 13px 210px 13px 24px extracted_at: "2026-06-11T05:01:14.583Z" completeness: 79 scoreVersion: "v2" --- # Design System — jitter.video > Extracted automatically by Prism from https://jitter.video/?noredir=1 > 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 jitter.video uses a pure-white canvas (`#ffffff`), letting typography, color and imagery carry the visual weight. Headlines are set in **TWK Lausanne**, a sans-serif display face (the dominant type signature, e.g. "Superfast motion for every team" at 80px). A second display voice — **Inter** (sans) — appears in lower bands (e.g. "Scale your animations for marketing, ads, brand, and product"), used for editorial accent. Body text is set in **Inter**. Headlines use weight 800 for confident, assertive presence — the brand wants to be heard. Negative letter-spacing at display sizes (-2.4px at 80px) compresses headlines into engineered blocks, dense and precise. Body text reads in Primary Color (`#19171c`) — softened from pure black, a small but deliberate detail that lowers reading friction. **Pure White** (`#ffffff`) provides interactive distinction without visual aggression. Elevation is built from multi-layer shadow stacks (9 distinct) — each combines several blurred layers at varying offsets to build a clear front-to-back hierarchy. Motion design uses smooth easing curves for polished state transitions. **Key Characteristics:** - Background: Pure White (`#ffffff`) - Primary typeface: Inter - Primary text: Primary Color (`#19171c`) - Accent: Pure White (`#ffffff`) - Display: 80px weight 800, letter-spacing -2.4px - Shadow system: 9 distinct elevation levels - Custom fonts loaded: Inter, Euclid Circular B, TWK Lausanne ## 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 - **lining figures** (`lnum`) — full-height numbers, more authoritative than old-style - **stylistic sets** (`ss0X`) — alternate letterforms enabled (often for brand-specific glyph variants) **Clone instruction:** Enable these in your CSS: ```css body { font-feature-settings: "tnum", "lnum", "ss01"; } ``` ## 4. Component Stylings ### Buttons **Ghost** - Background: `transparent` - Text: `#19171c` `{colors.ink-muted}` - Padding: 10px - Radius: 0px - Font: 18px weight 600 - Use: Subtle action, toolbar, nav button - Focus: opacity: `1`, transform: `matrix(1, 0, 0, 1, 0, 0)`, outline: `rgb(16, 16, 16) auto 1px` ### Inputs & Forms **Text Input** - Background: `#2d2933` - Text: `#ffffff` `{colors.primary}` - Padding: 13px 210px 13px 24px - Radius: 0px 50px 50px 0px - Border: 1px solid rgba(255, 255, 255, 0.1) - Font: 17px weight 600 - Use: Text fields, search inputs - Focus: outline: `rgb(255, 255, 255) none 3px` ### Status Badges **Neutral Dark** - Background: `transparent` - Text: `#19171c` `{colors.ink-muted}` - Padding: 7px 20px - Radius: 40px - Font: 15px weight 400 - Use: Status indicator, label, pill **Neutral Dark** - Background: `transparent` - Text: `#17082c` - Padding: 5px 20px - Radius: 40px - Font: 20px weight 600 - Use: Status indicator, label, pill ### Alerts **Alert Banner** - Background: `transparent` - Text: `#ff0000` - Padding: 13px 210px 13px 24px - Radius: 0px - Font: 16px weight 400 - Use: System alert, banner notification, toast ## 4b. Component Behaviors (State Matrix) ### Interaction State Narrative - **Button**: - **focus:** transform applied *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: "rgb(25, 23, 28)" focus: bg: "transparent" fg: "inherit" input: default: bg: "rgb(45, 41, 51)" fg: "rgb(255, 255, 255)" border: "1px solid rgba(255, 255, 255, 0.1)" focus: bg: "transparent" fg: "inherit" link: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(25, 23, 28)" card: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(255, 255, 255)" navLink: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(25, 23, 28)" badge: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(25, 23, 28)" footerLink: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(255, 255, 255)" ``` **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 - **1 shape(s)** in this system: `Ghost` - **DO NOT introduce new buttons variants** without justification ### Inputs & Forms - **1 shape(s)** in this system: `Text Input` - **DO NOT introduce new inputs & forms variants** without justification ### Status Badges - **1 shape(s)** in this system: `Neutral Dark` - **DO NOT introduce new status badges variants** without justification ### Alerts - **1 shape(s)** in this system: `Alert Banner` - **DO NOT introduce new alerts variants** without justification ## 5. Layout Principles ### Layout Type **hero + sections** ### Grid Single column, centered content ### Max Width 1200px ### Spacing System Compact spacing — information density prioritized | Token | Value | |-------|-------| | xxs | 2px | | xs | 5px | | sm | 13px | | md | 24px | | base | 30px | | lg | 37px | | xl | 40px | | 2xl | 60px | | 3xl | 70px | ### Border Radius Scale | Name | Value | Use | |------|-------|-----| | None | 0px | No rounding | | Xs | 18px | Tiny corners (badges, micro elements) | | Sm | 20px | Buttons, inputs, small elements | | Md | 26px | Cards, containers | | Lg | 40px | Large rounded elements, pill segments | | Xl | 50px | Category strips, featured containers | | Full | 9999px | Pills, avatars, circular elements | ### Shape Language | Component | Border Radius | |-----------|---------------| | Buttons | `0px` | | Inputs & Forms | `0px 50px 50px 0px` | | Status Badges | `40px` | | Alerts | `0px` | | Page Body | `0px` | | Navigation | `0px` | | Primary Input | `0px 50px 50px 0px` | **Shape Personality**: Generously Rounded — Soft, friendly corners (8px+). Approachable, consumer-facing feel. **Full Radius Spectrum**: 0px, 18px, 20px, 26px, 40px, 50px, 375px (from `allBorderRadii` scan) ## 5b. Spacing Rhythm Names **Measured section padding**: bands use ~70px internal vertical padding (up to 2345px) — **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** | `70px` | Top/bottom of full-bleed hero sections | | **section** | `40px` | Between major bands (color change, content shift) | | **subsection** | `37px` | Within a section, between content groups | | **card** | `24px` | Card padding, list-item spacing | | **compact** | `13px` | Form fields, tight clusters, badge padding | | **micro** | `5px` | 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). **6/8 structural patterns detected.** ### Hero Pattern - **Composition:** centered — Centered composition — heading + subheading + CTAs stacked vertically, content centered horizontally. Common for SaaS marketing pages. - **Viewport coverage:** 299px tall (not full-viewport) - **Heading:** "Superfast motion for every team" — 80px center-aligned - **Subheading:** "Jitter AI: Build your own creative tools Learn more" - **CTAs:** 1 (primary: "Jitter AI: Build your own creative tools Learn more") - **Clone instruction:** Reproduce the **centered** 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. ### Navigation Pattern - **Position:** static (scrolls with page) - **Layout:** unknown — Layout not classified - **Height:** 90px - **Logo:** ✗ absent - **Nav links:** 10 primary items - **CTAs in nav:** 0 (no buttons — links only) - **Clone instruction:** Build a static unknown navigation. Link-only — no button styling needed. ### Card Grid Pattern - **Card count:** 4 cards detected - **Columns (desktop):** 3-up grid - **Card dimensions:** 460×575px (aspect 0.8:1) - **Gap:** 20px between cards - **Content:** ✗ no image - **Clone instruction:** Build a 3-column grid (desktop) with cards at ~0.8:1 aspect ratio. Text/icon-only cards (no photography). ### Pricing Table Pattern - **Tier count:** 2 pricing tiers - **Layout:** vertical stacked - **Columns (desktop):** 2-up - **Feature list:** ✓ (median ~21 feature points per tier) - **Clone instruction:** Build a 2-column vertical-stack pricing comparison. ### Testimonial Pattern - **Count:** 14 testimonial blocks - **Layout:** grid - **Avg quote length:** 72 chars (short blurb) - **Includes:** ✓ avatars | ✗ no logos | ✗ no ratings - **Clone instruction:** Build a grid of 14 testimonials. Each includes an avatar. ### Footer Pattern - **Columns:** 5 - **Links:** 37 total - **Height:** 2017px - **Includes:** ✓ newsletter signup | ✓ social icons | ✓ copyright - **Clone instruction:** Build a 5-column footer with ~7 links per column, newsletter signup, social media links, and a copyright line. ## 6.

Do's and Don'ts ### Do - Use Primary Color (`#19171c`) 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 (-2.4px) at display sizes for compressed, editorial headlines - Use the extracted shadow patterns for elevation — they are tuned to match the brand palette - Use Pure White (`#ffffff`) as the primary accent — it's the brand's signature interactive color - Style form inputs with a `1px solid rgba(255, 255, 255, 0.1)` border — use border-based inputs, not floating labels or underline-only - Maintain nav height at 90px — consistent vertical space for the navigation bar - Respect the 5px–40px spacing range — the design uses a wide scale for visual breathing room - Use a single primary CTA in the hero — the design intentionally avoids choice paralysis - Use a 3-column grid on desktop — density matters for this content type - Show person avatars with testimonials — social proof is human-centric here - Lay out testimonials in a grid (14+ items) — quantity signals scale and trust - Include a newsletter signup in the footer — email capture is part of the conversion funnel - Build a content-dense footer (5 columns, ~37 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 invent new shadow values — use only the extracted shadow levels - Don't introduce additional saturated accent colors — the palette is intentionally controlled - Don't remove the input border — the border is the primary affordance indicator for form fields - Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence - Don't make the nav sticky — this design lets it scroll away to maximize content focus - Don't put a CTA button in the nav — this design uses links only at the top ## 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(255, 255, 255)` for primary CTAs and brand-mark signals only" why: "Single chromatic assertion device — overuse dilutes meaning" test: "querySelectorAll('[style*=\"rgb(255, 255, 255)\"]').length <= 3 per fold" ``` ## 9. Responsive Behavior ### Breakpoints | Name | Width | Key Changes | |------|-------|-------------| | Mobile | 380px | Single column, compact spacing | | Mobile | 480px | Single column, compact spacing | | Mobile Large | 640px | Expanded mobile layout | | Mobile Large | 720px | Expanded mobile layout | | Mobile Large | 767px | Expanded mobile layout | | Tablet | 1024px | Multi-column grids begin | | Desktop | 1280px | Full feature layout | | Large Desktop | 1440px | Maximum content width | ### Token Diff — Desktop vs Mobile | Element | Property | Desktop | Mobile | |---------|----------|---------|--------| | heading | font-size | `80px` | `64px` | | heading | line-height | `72px` | `53.76px` | | nav | display | `block` | `none` | | nav | height | `90px` | `auto` | | hero | padding | `190px 0px 30px` | `140px 0px 40px` | | hero | height | `1193.34px` | `935.547px` | | card | width | `258.781px` | `100%` | ### Collapsing Strategy - Headlines: 80px → 64px on mobile - Navigation: block → none 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): - **Card grid: 3-up → 1-up** — cards stack as viewport narrows, becoming a vertical list on mobile. - **Footer columns collapse:** 5 columns (desktop) → 3 columns (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.* - **Canvas / 2D rendering** — animated/interactive canvas (charts, graphs, particle fields). Reproduce as live data-viz (e.g. an animated SVG/Canvas line chart), NOT a static image. - **Clip-path shapes** — 8 non-rectangular cut(s). - **Scroll-driven reveals** — content animates in on scroll (CSS scroll-timeline). Build fade/translate reveal-on-scroll for below-fold bands. - **CSS-variable animations** (3) — animated custom properties. > **Motion fingerprint**: Canvas 2D, non-rectangular shapes (10), CSS scroll-driven animations ## 9b. Visual Tone & Photography **Tone:** Photography-driven The site is dominated by photography (JPG/WebP). Photos carry the brand voice as much as the typography. Use authentic, brand-appropriate imagery — generic stock will degrade quality. **Canonical Brand Image (OG):** - https://jitter.video/static/homepage-2026-f84088ec66bb835cbedee56b8e494ab3.png *This is the image shown when the site is shared on social media — represents the brand visual essence.* **Aspect Ratio Distribution:** - Landscape (1.15–2.3): 14 (21%) - Portrait (<0.87): 4 (6%) - Square (0.87–1.15): 49 (72%) - Ultra-wide (>2.3): 1 (1%) **Media Format Mix:** - JPG: 4 (typically photographic content) - WebP: 20 (optimized photo/illustration hybrid) - PNG: 43 (logos, transparent UI elements, mockups) - SVG: 8 (icons, illustrations, decorative geometry) **Average rendered image size:** 110×102px **Above-fold image count:** 0 / 68 **Decorative Patterns Detected:** - 7 large decorative SVG shapes (≥200×200px, non-icon) — likely blob/illustration accents **Clone instruction for decorative work:** Decorative SVG accents are part of the brand — generate or source blob/illustration shapes to scatter behind content. **Imagery Guidance for clones:** - Source authentic photography (or licensed stock that matches the brand mood) — placeholders will visibly degrade the clone. - Match the dominant aspect ratio (see above) so card grids and hero compositions hold. ## 10. Agent Prompt Guide ### Quick Reference - Background: Pure White (`#ffffff`) - Primary text: Primary Color (`#19171c`) - Accent: Pure White (`#ffffff`) - Border: Light Grey (`#c3c3c6`) - Font: Inter - Body: 12px weight 400 ### Example Component Prompts - "Create a hero section on Pure White background (#ffffff). Headline at 80px Inter weight 800, line-height 0.9, letter-spacing -2.4px, color #19171c." - "Create the primary CTA button: `#ffffff` background, `#ffffff` text, 9999px border-radius, 14px 27px padding, 600 weight, Inter font." - "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 0px." - "Build navigation: static on `#ffffff`. Inter 18px 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**: Pure White (`#ffffff`) is the sole interactive color. On hover → #a981ff (`#a981ff`). Use CSS transitions, not opacity/brightness filters. 4. **Motion**: All transitions use physics-based spring curves. Never use linear for UI transitions — preserve the brand's easing personality. 5. **Shape**: CTAs at `0px`, cards at `0px`. Apply border-radius from the extracted scale only — don't invent intermediate values. 6. **Spacing**: Use the `--ca-space-*` token scale (5px–40px). 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.

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: - "Motion design made simple" - "“Jitter gives you no excuse to skip motion . It’s that easy.”" - "Built for teams who move fast" - "“We couldn’t believe you can create such polished animations in no time at all.”" - "Everything your team needs to collaborate and deliver their best work" - "Animate for social media, ads, marketing, brand, product, and more" sub-headings: - "Import from Figma" - "A brand-new way to design and animate" - "Unlock collaboration" - "Jitter AI: Build your own creative tools Learn more" - "Motion doesn’t have to be hard. With Jitter, any designer can create professional animations in minu" - "Import from Figma" ctas: - "Skip to main content" - "Try for free" - "Try Jitter for free" - "Explore all the features" - "Social media" - "Browse 300+ free templates" - "Read customer stories" navigation: - "Product" - "Customers" - "Counters" - "Components" - "Glass effect" - "Creative teams" - "Agencies" - "Studios" - "Templates" - "Pricing" footer-links: - "Get started for free" - "Product" - "Import from Figma" - "After Effects alternative" ``` **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: logo: count: 16 avg-ratio: 2.02 common-aspect: "~16:9 landscape" sample-alts: - "Google" - "Gamma" - "Perplexity" product: count: 8 avg-ratio: 1.02 common-aspect: "~1:1 square" sample-alts: - "video poster image" - "video poster image" - "video poster image" editorial: count: 1 avg-ratio: 0.49 common-aspect: "~9:21 tall" sample-alts: - "video poster image" thumbnail: count: 10 avg-ratio: 1.00 common-aspect: "~1:1 square" sample-alts: - "Matt Sewell" - "Phi Hoang" - "Rico Supply" ``` **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 `10px` · radius `0px` · weight `600`_ ### Generic Card ```html
``` _Source pattern detected: padding `0px` · radius `0px` · shadow `none`_ **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** 1 · **cta** 4 · **auth** 1 · **product** 11 · **pricing** 2 · **blog** 5 · **project** 16 · **social** 4 · **footer** 2 · **other** 14 **Primary actions (conversion path):** - Account access — "Log in" (login/signup) → `https://jitter.video/login/` - Primary call-to-action — "Try for free" (the conversion path) → `https://jitter.video/join/` - Primary call-to-action — "Try Jitter for free" (the conversion path) → `https://jitter.video/join/` - Primary call-to-action — "Get started now" (the conversion path) → `https://jitter.video/join/` - Primary call-to-action — "Get started for free" (the conversion path) → `https://jitter.video/join/` **Projects / case studies detected** (clustered by URL + featured image): *Templates* — medium confidence, 6 items: | Title | Featured image | Link | |---|---|---| | Devices | — | https://jitter.video/templates/devices/ | | Text animations | — | https://jitter.video/templates/text/ | | Logos | — | https://jitter.video/templates/logos/ | | Animated icons | — | https://jitter.video/templates/icons/ | | Charts | — | https://jitter.video/templates/charts/ | | Animated websites | — | https://jitter.video/templates/websites/ | *Customers* — medium confidence, 3 items: | Title | Featured image | Link | |---|---|---| | Perplexity | — | https://jitter.video/customers/perplexity/ | | 27b | — | https://jitter.video/customers/27b/ | | Deliveroo | — | https://jitter.video/customers/deliveroo/ | **Signals:** 9/60 links carry a featured image · dominant link roles: inline-link (21), footer-link (20), content-card (16). --- ## Extraction Completeness: 79/100 (B) | Category | Score | Max | Detail | |----------|-------|-----|--------| | Colors & Palette | 25 | 25 | 20 named colors | | Typography | 20 | 20 | 10 roles defined | | Components | 16 | 20 | 4 specs extracted | | Motion & Interaction | 12 | 15 | Keyframes | | CSS Custom Properties | 1 | 10 | 29 vars | | Responsive Breakpoints | 5 | 5 | 8 breakpoints | | Variable Fonts | 0 | 5 | None detected | ## 12.
