--- version: alpha name: sentry.io description: "Dark-canvas product system built on #1f1633 with #79628c as the single brand accent. Type anchored in Dammit Sans at 88px / weight 700. Extracted automatically from https://sentry.io/ — rendered styles via getComputedStyle() + CSS custom properties (token-only values may not be painted)." narrative: | sentry.io is built on a near-black canvas (rgb(31, 22, 51)). The system uses rgb(121, 98, 140) as the singular interactive color. Moderately rounded CTAs (8px) — modern SaaS standard, neither sharp nor pill alongside Dammit Sans as the primary typeface. A layered elevation system (6 distinct shadows) building a clear front-to-back hierarchy. Motion is a first-class concern — 10 keyframe animations plus transition-driven interactions. colors: canvas: "#1f1633" surface-1: "#1f1633" surface-2: "#150f23" ink: "#ffffff" ink-muted: "#9093c1" ink-subtle: "#9093c1" primary: "#79628c" on-primary: "#111111" primary-hover: "#6a5fc1" hairline: "rgba(255, 255, 255, 0.18)" typography: display-xl: fontFamily: "Dammit Sans, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 88px fontWeight: 700 lineHeight: 1.2 letterSpacing: 0 display-md: fontFamily: "Rubik, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 24px fontWeight: 500 lineHeight: 1.25 letterSpacing: 0 body: fontFamily: "Rubik, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 16px fontWeight: 400 lineHeight: 2 letterSpacing: 0 caption: fontFamily: "Monaco, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 16px fontWeight: 400 lineHeight: 1.5 letterSpacing: 0 button: fontFamily: "Rubik, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 14px fontWeight: 500 lineHeight: 1.29 letterSpacing: 0.2px eyebrow: fontFamily: "Rubik, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 27px fontWeight: 500 lineHeight: 1.25 letterSpacing: 0 mono: fontFamily: "Rubik, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 16px fontWeight: 500 lineHeight: 1.5 letterSpacing: 0 rounded: none: 0px xs: 4px sm: 8px md: 13px lg: 18px xl: 9999px spacing: xxs: 2px xs: 4px sm: 8px md: 12px lg: 24px xl: 32px xxl: 64px components: button-light--invert: backgroundColor: "#efefef" textColor: "#1a1a1a" typography: "{typography.button}" rounded: "{rounded.sm}" padding: 12px 16px button-ghost: backgroundColor: "transparent" textColor: "{colors.hairline}" typography: "{typography.button}" rounded: "{rounded.sm}" padding: 12px 16px button-ghost-2: backgroundColor: "transparent" textColor: "{colors.hairline}" typography: "{typography.button}" rounded: "{rounded.sm}" padding: 12px 16px input-text-input: backgroundColor: "{colors.hairline}" textColor: "{colors.surface-1}" typography: "{typography.body}" rounded: "{rounded.xs}" padding: 8px 12px extracted_at: "2026-06-11T05:02:22.779Z" completeness: 73 scoreVersion: "v2" --- # Design System — sentry.io > Extracted automatically by Prism from https://sentry.io > 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 sentry.io commits fully to dark-mode as the native medium, not as a toggled alternative. The canvas is a dark surface (`#1f1633`) where elevation is communicated through subtle white-opacity gradations rather than traditional shadows — semi-transparent white borders act as the primary depth indicator, like wireframes etched in moonlight. Headlines are set in **Dammit Sans**, a sans-serif display face (the dominant type signature, e.g. "Code fix it faster" at 88px). A second display voice — **Rubik** (sans) — appears in lower bands (e.g. "Application monitoring software considered "not bad" by mill"), used for editorial accent. Body text is set in **Rubik**. Headlines use weight 700 for confident, assertive presence — the brand wants to be heard. Body text reads in Pure White (`#ffffff`). **Slate Gray** (`#79628c`) provides interactive distinction without visual aggression. Elevation is built from multi-layer shadow stacks (6 distinct) — each combines several blurred layers at varying offsets to build a clear front-to-back hierarchy. 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: Deep Navy (`#1f1633`) - Primary typeface: Rubik - Primary text: Whitesmoke (`#e5e7eb`) - Accent: Slate Gray (`#79628c`) - Display: 88px weight 700 - Shadow system: 6 distinct elevation levels - Custom fonts loaded: Rubik, Dammit Sans ## 2.

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: "rgb(239, 239, 239)" fg: "rgb(26, 26, 26)" border: "2px solid rgba(0, 0, 0, 0)" input: default: bg: "rgb(255, 255, 255)" fg: "rgb(31, 22, 51)" border: "1px solid rgb(207, 207, 219)" shadow: "rgba(0, 0, 0, 0.15) 0px 2px 10px 0px inset" link: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(255, 255, 255)" navLink: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(255, 255, 255)" tab: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(255, 255, 255)" badge: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(249, 117, 131)" footerLink: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(255, 255, 255)" hover: bg: "transparent" fg: "inherit" ``` **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 - **4 shape(s)** in this system: `Light / Invert`, `Ghost`, `Pill`, `Icon Button` - **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 ## 5. Layout Principles ### Layout Type **top-nav + content** ### Grid Single column, centered content ### Max Width 1200px ### Spacing System Compact spacing — information density prioritized | Token | Value | |-------|-------| | xxs | 2px | | xs | 4px | | sm | 8px | | md | 12px | | base | 16px | | lg | 24px | | xl | 32px | | 2xl | 44px | | 3xl | 64px | ### Border Radius Scale | Name | Value | Use | |------|-------|-----| | None | 0px | No rounding | | Xs | 4px | Tiny corners (badges, micro elements) | | Sm | 8px | Buttons, inputs, small elements | | Md | 13px | Cards, containers | | Lg | 18px | Large rounded elements, pill segments | | Xl | 9999px | Category strips, featured containers | | Full | 9999px | Pills, avatars, circular elements | ### Shape Language | Component | Border Radius | |-----------|---------------| | Buttons | `8px` | | Inputs & Forms | `6px` | | Page Body | `0px` | | Navigation | `0px` | | Primary Input | `6px` | **Shape Personality**: Moderate Rounding — Medium corners (4–12px). Modern SaaS standard, neither sharp nor pill. **Full Radius Spectrum**: 0px, 4px, 6px, 8px, 10px, 10.6px, 12px, 13px (from `allBorderRadii` scan) ## 5b. Spacing Rhythm Names **Measured section padding**: bands use ~44px internal vertical padding (up to 64px) — **standard**. (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** | `32px` | Between major bands (color change, content shift) | | **subsection** | `24px` | Within a section, between content groups | | **card** | `12px` | Card padding, list-item spacing | | **compact** | `8px` | Form fields, tight clusters, badge padding | | **micro** | `4px` | 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). **5/8 structural patterns detected.** ### Hero Pattern - **Composition:** centered — Centered composition — heading + subheading + CTAs stacked vertically, content centered horizontally. Common for SaaS marketing pages. - **Viewport coverage:** 106px tall (not full-viewport) - **Heading:** "Code breaks, fix it faster" — 88px center-aligned - **CTAs:** none detected in hero (unusual — agent should verify) - **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:** 72px - **Logo:** ✓ present - **Nav links:** 1 primary items - **CTAs in nav:** 4 - **Theme toggle:** ✓ dark/light mode switcher present - **Clone instruction:** Build a static unknown navigation. Reserve 4 slots for primary CTAs. ### Card Grid Pattern - **Card count:** 4 cards detected - **Columns (desktop):** 3-up grid - **Card dimensions:** 520×302px (aspect 1.72:1) - **Gap:** 48px between cards - **Content:** ✓ image - **Image position:** top - **Clone instruction:** Build a 3-column grid (desktop) with cards at ~1.72:1 aspect ratio. Each card has an image at the top. ### Testimonial Pattern - **Count:** 5 testimonial blocks - **Layout:** grid - **Avg quote length:** 24 chars (short blurb) - **Includes:** ✗ no avatars | ✗ no logos | ✗ no ratings - **Clone instruction:** Build a grid of 5 testimonials. ### Footer Pattern - **Columns:** 4 - **Links:** 38 total - **Height:** 743px - **Includes:** ✗ no newsletter | ✓ social icons | ✓ copyright - **Clone instruction:** Build a 4-column footer with ~10 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 | | Layered (Level 1) |
`rgba(0, 0, 0, 0.1) 0px 10px 15px -3px`,
`rgba(0, 0, 0, 0.1) 0px 4px 6px -4px` | Cards, elevated surfaces | | Layered (Level 2) |
`rgba(0, 0, 0, 0.08) 0px 2px 8px 0px` | Cards, elevated surfaces | | Inset (Level 3) |
`rgba(0, 0, 0, 0.1) 0px 1px 3px 0px inset` | Buttons, pressed-state elements | | Layered (Level 4) |
`rgba(0, 0, 0, 0.2) 0px 1px 3px 0px` | Cards, elevated surfaces | **Shadow Philosophy**: Multi-layered shadow system creating natural, atmospheric depth. Each shadow level combines multiple layers for realistic elevation. ## 7. Motion & Interaction ### Dominant Easing Curves | Curve | Semantic Name | |-------|---------------| | `cubic-bezier(0.4,0,0.2,1)` | Material Standard — Balanced | | `ease` | CSS ease — Default | | `ease-out` | Ease Out — Decelerating | ### Duration Scale | Value | Tier | Typical Use | |-------|------|-------------| | `200ms` | Normal | Panel open/close, navigation | | `300ms` | Normal | Panel open/close, navigation | | `800ms` | Cinematic | Splash, marketing reveals | ### Copy-Paste Transition Snippets **Color / Background** ```css transition: color 0.2s cubic-bezier(0.4, 0, 0.2, 1), background-color 0.2s cubic-bezier(0.4, 0, 0.2, 1), border-color 0.2s cubic-...; ``` **All Props** ```css transition: 0.2s cubic-bezier(0.4, 0, 0.2, 1); ``` **All Props** ```css transition: margin-right 0.2s, margin-left 0.2s; ``` **Background** ```css transition: background 0.2s ease-out; ``` ### Keyframe Animation Catalog | Animation Name | Type | Animated Props | Use Hint | |----------------|------|----------------|----------| | `fadeIn` | Fade | opacity | Element entrance | | `float` | Slide | transform | UI transition | | `logo-rock` | Rotate / Spin | transform | UI transition | | `scroll-x` | Slide | transform | UI transition | | `expandSnippet` | Fade | max-height, opacity | UI transition | | `shrinkSnippet` | Fade | max-height, opacity | UI transition | | `swingDown` | Rotate / Spin | transform | UI transition | | `pushUp` | Rotate / Spin | transform | UI transition | | `_spin_1vwuf_1` | Rotate / Spin | transform | Loading indicator | | `_thumbRotation_1vwuf_1` | Rotate / Spin | transform | UI transition | ### Motion Fingerprint - **Speed Character**: Deliberate & Calm (median duration: `300ms`) - **Dominant Easing**: custom cubic-bezier curves - **Animation Library**: 10 unique animations (10 total including variants) > This design moves with deliberate & calm timing using custom cubic-bezier curves, creating a UI that feels calm and controlled. ## 8. Do's and Don'ts ### Do - Use dark background (`#1f1633`) as the foundation — this is a dark-mode-native design - Use Rubik as the primary typeface — it defines the brand personality - Use the extracted shadow patterns for elevation — they are tuned to match the brand palette - Use full-pill radius (9999px) only for specific elements (avatars, pills, toggles) - Use Slate Gray (`#79628c`) as the primary accent — it's the brand's signature interactive color - Use 8px border-radius on buttons — the standard corner rounding for interactive elements - Style form inputs with a `1px solid rgb(207, 207, 219)` border — use border-based inputs, not floating labels or underline-only - Maintain nav height at 72px — consistent vertical space for the navigation bar - Respect the 4px–32px spacing range — the design uses a wide scale for visual breathing room - Include a theme toggle in the nav — dark mode is a first-class feature - Each card includes a top image — imagery is part of the card identity, not optional - Use a 3-column grid on desktop — density matters for this content type - Lay out testimonials in a grid (5+ items) — quantity signals scale and trust - Build a content-dense footer (4 columns, ~38 links) — this site treats the footer as a sitemap, not an afterthought ### Don't - Don't use light backgrounds — the dark canvas is the native medium - Don't substitute with generic sans-serif or serif — the custom font carries the brand - Don't invent new shadow values — use only the extracted shadow levels - 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 - 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 ## 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(31, 22, 51)` as the base canvas" why: "Every component is designed to composit against this exact tone" test: "document.body.style.backgroundColor === 'rgb(31, 22, 51)'" - id: brand-accent-001 type: do rule: "Reserve `rgb(121, 98, 140)` for primary CTAs and brand-mark signals only" why: "Single chromatic assertion device — overuse dilutes meaning" test: "querySelectorAll('[style*=\"rgb(121, 98, 140)\"]').length <= 3 per fold" ``` ## 9. Responsive Behavior ### Breakpoints | Name | Width | Key Changes | |------|-------|-------------| | Mobile Large | 576px | Expanded mobile layout | | Mobile Large | 640px | Expanded mobile layout | | Mobile Large | 767px | Expanded mobile layout | | Tablet | 1024px | Multi-column grids begin | | Desktop | 1151px | Full feature layout | | Large Desktop | 1440px | Maximum content width | ### Token Diff — Desktop vs Mobile | Element | Property | Desktop | Mobile | |---------|----------|---------|--------| | heading | font-size | `88px` | `50.19px` | | heading | font-weight | `700` | `500` | | heading | line-height | `105.6px` | `60.228px` | | button | width | `auto` | `94.8125px` | ### Collapsing Strategy - Headlines: 88px → 50.19px 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: 12px 16px 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): - **Navigation collapses to hamburger** — 1 links visible on desktop, 0 on mobile (the rest hide behind a menu toggle). - **Nav CTAs reduced** on mobile (4 → 0) — the design prioritizes content over conversion buttons at small sizes. - **Card grid: 3-up → 1-up** — cards stack as viewport narrows, becoming a vertical list 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.* - **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. - **Glassmorphism** — 1 frosted/blur layer(s) (e.g. `blur(18px) saturate(1.8)`). - **Clip-path shapes** — 8 non-rectangular cut(s). > **Motion fingerprint**: Canvas 2D, glassmorphism (1 layers), non-rectangular shapes (10) ## 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://sentry.io/_astro/home-hero-meta.DJDejDMD.webp *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: 0.78:1 (portrait / vertical) - Rendered size: 240×307px - *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): 8 (57%) - Portrait (<0.87): 1 (7%) - Square (0.87–1.15): 1 (7%) - Ultra-wide (>2.3): 4 (29%) **Media Format Mix:** - WebP: 3 (optimized photo/illustration hybrid) - SVG: 3 (icons, illustrations, decorative geometry) **Average rendered image size:** 498×294px **Above-fold image count:** 0 / 14 **Decorative Patterns Detected:** - 24 multi-stop linear gradients (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth - 1 radial gradient — circular color blooms used for spotlight/glow effects - 3 large decorative SVG shapes (≥200×200px, non-icon) — likely blob/illustration accents - **Glassmorphism** detected (`backdrop-filter: blur`) — layered transparent surfaces with blur, modern OS-like aesthetic **Clone instruction for decorative work:** This is a gradient-rich design — invest in multi-stop CSS gradients (3+ color stops), not solid backgrounds. **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: Deep Navy (`#1f1633`) - Primary text: Pure White (`#ffffff`) - Accent: Slate Gray (`#79628c`) - Border: Translucent Pure White (18%) (`rgba(255, 255, 255, 0.18)`) - Font: Rubik - Body: 16px weight 400 ### Example Component Prompts - "Create a hero section on Deep Navy background (#1f1633). Headline at 88px Rubik weight 700, line-height 1.2, color #ffffff." - "Create the primary CTA button: `#79628c` background, `#1a1a1a` text, 8px border-radius, 12px 16px padding, 500 weight, Rubik font." - "Build navigation: static on `#1f1633`. Rubik 16px weight 400 for links." ### Iteration Guide 1. **Canvas**: Set the dark canvas to Deep Navy (`#1f1633`) — every component is composited against this exact base. 2. **Typography**: All type in Rubik, weight range 400–700. Never exceed 700 — heavier weights break the brand's tonal restraint. 3. **Accent**: Slate Gray (`#79628c`) is the sole interactive color. On hover → Slate Blue (`#6a5fc1`). Use CSS transitions, not opacity/brightness filters. 4. **Motion**: All transitions use `cubic-bezier(0.4,0,0.2,1)`. Never use linear for UI transitions — preserve the brand's easing personality. 5. **Shape**: CTAs at `8px`. Apply border-radius from the extracted scale only — don't invent intermediate values. 6. **Spacing**: Use the `--ca-space-*` token scale (4px–32px). 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-surface-1: #1f1633; --ca-surface-2: #150f23; --ca-hairline: #ffffff; --ca-ink-subtle: #9093c1; --ca-primary: #79628c; --ca-on-primary: #111111; --ca-primary-hover: #6a5fc1; } /* Typography */ :root { --ca-font-primary: "Dammit Sans", system-ui, sans-serif; --ca-text-display: 88px; --ca-text-body: 16px; --ca-text-caption: 16px; --ca-text-button: 14px; --ca-text-mono: 16px; } /* Spacing & Radius */ :root { --ca-space-xxs: 2px; --ca-space-xs: 4px; --ca-space-sm: 8px; --ca-space-md: 12px; --ca-space-base: 16px; --ca-space-lg: 24px; --ca-space-xl: 32px; --ca-space-2xl: 44px; --ca-space-3xl: 64px; --ca-radius-none: 0px; --ca-radius-xs: 4px; --ca-radius-sm: 8px; --ca-radius-md: 13px; --ca-radius-lg: 18px; --ca-radius-xl: 9999px; --ca-radius-full: 9999px; } ``` ## 13. Page Structure Skeleton *The actual layout the source site uses. Reproduce these sections in order to match the site structure.* ```yaml page-skeleton: - section: hero tag: main classes: ["transition-colors", "duration-200", "bg-rich-black"] height: 7886px width: full-bleed layout: block children: 11 bg: "rgb(31, 22, 51)" tone: dark vertical-padding: ~64px (generous) contains: chart/canvas (reproduce as live data-viz, not a flat image) - section: feature-section tag: section classes: ["relative", "overflow-x-clip", "z-0", "pb-4"] height: 1051px width: full-bleed layout: block children: 1 vertical-padding: ~32px contains: chart/canvas (reproduce as live data-viz, not a flat image) padding: "0px 0px 64px" - section: feature-section tag: div classes: ["container"] height: 447px width: 1152px layout: block children: 1 vertical-padding: ~64px (generous) padding: "64px 32px" - section: feature-section tag: div classes: ["content-wrapper"] height: 1723px width: full-bleed layout: block children: 2 vertical-padding: ~64px (generous) contains: chart/canvas (reproduce as live data-viz, not a flat image) - section: content-section tag: section classes: ["relative", "overflow-x-clip", "z-0", "pt-4"] height: 672px width: full-bleed layout: block children: 1 vertical-padding: ~64px (generous) padding: "64px 0px" - section: content-section tag: div classes: ["container"] height: 544px width: 1152px layout: block children: 3 vertical-padding: ~64px (generous) padding: "64px 32px" - section: unknown tag: div classes: ["animated-logo-grid-wrapper", "faded-edges"] height: 416px width: 1088px layout: block children: 2 vertical-padding: ~40px padding: "40px 0px" - section: unknown tag: div height: 307px width: 1088px layout: flex-row justify=center children: 1 - section: feature-section tag: section classes: ["relative", "overflow-x-clip", "z-0", "pb-4"] height: 947px width: full-bleed layout: block children: 1 vertical-padding: ~32px padding: "0px 0px 64px" - section: feature-section tag: div classes: ["container", "disable-padding-top"] height: 883px width: 1152px layout: block children: 3 vertical-padding: ~32px padding: "0px 32px 64px" - section: feature-section tag: div classes: ["content-wrapper"] height: 947px width: full-bleed layout: block children: 1 vertical-padding: ~32px - section: feature-section tag: section classes: ["relative", "overflow-x-clip", "z-0", "pb-4"] height: 999px width: full-bleed layout: block children: 1 vertical-padding: ~32px padding: "0px 0px 64px" - section: feature-section tag: section classes: ["w-full", "p-0", "border-0"] height: 807px width: 1088px layout: block children: 2 - section: feature-section tag: div classes: ["container", "disable-padding-top"] height: 935px width: 1152px layout: block children: 2 vertical-padding: ~32px padding: "0px 32px 64px" - section: feature-section tag: div classes: ["content-wrapper"] height: 1988px width: full-bleed layout: block children: 2 vertical-padding: ~32px - section: faq tag: div classes: ["accordion-wrapper", "flex", "flex-col", "self-start"] height: 386px width: 411px layout: flex-column justify=normal children: 3 - section: feature-section tag: section classes: ["relative", "overflow-x-clip", "z-0", "pb-4"] height: 989px width: full-bleed layout: block children: 1 vertical-padding: ~32px padding: "0px 0px 64px" - section: feature-section tag: section classes: ["w-full", "p-0", "border-0"] height: 797px width: 1088px layout: block children: 2 - section: feature-section tag: div classes: ["container", "disable-padding-top"] height: 925px width: 1152px layout: block children: 2 vertical-padding: ~32px padding: "0px 32px 64px" - section: faq tag: div classes: ["accordion-wrapper", "flex", "flex-col", "self-start"] height: 420px width: 411px layout: flex-column justify=normal children: 3 - section: feature-section tag: section classes: ["relative", "overflow-x-clip", "z-0", "pb-4"] height: 631px width: full-bleed layout: block children: 1 vertical-padding: ~32px padding: "0px 0px 64px" - section: feature-section tag: div classes: ["container", "disable-padding-top"] height: 567px width: 1152px layout: block children: 2 vertical-padding: ~32px padding: "0px 32px 64px" - section: feature-section tag: div classes: ["content-wrapper"] height: 631px width: full-bleed layout: block children: 1 vertical-padding: ~32px - section: feature-section tag: section classes: ["relative", "overflow-x-clip", "z-0", "pb-4"] height: 834px width: full-bleed layout: block children: 1 vertical-padding: ~32px padding: "0px 0px 64px" - section: feature-section tag: div classes: ["container", "disable-padding-top"] height: 770px width: 1152px layout: block children: 3 vertical-padding: ~32px padding: "0px 32px 64px" ``` **Agent rule**: rebuild sections in this order (sorted by vertical position). 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: - "Developer first. Always." - "Fix It" sub-headings: - "Monitor in five lines" - "Company" ctas: - "PLATFORM" - "GET DEMO" - "GET STARTED" - "Marketing Mode" navigation: - "Twitter Menu Button" - "Github Social Menu Button" - "LinkedIn Menu Button" - "Discord Menu Button" - "DOCS" - "PRICING" - "SIGN IN" - "GET DEMO" - "GET STARTED" - "ABOUT" footer-links: - "ABOUT" - "TERMS" - "Twitter Menu Button" ``` **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: 3 avg-ratio: 1.71 common-aspect: "~16:9 landscape" sample-alts: - "quote mark" - "quote mark" - "quote mark" product: count: 2 avg-ratio: 1.15 common-aspect: "~1:1 square" sample-alts: - "Left Installation Instructions Image" - "Right Installation Instructions Image" thumbnail: count: 7 avg-ratio: 1.00 common-aspect: "~1:1 square" sample-alts: - "Anthropic" - "Disney+" - "Instacart" ``` **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 `12px 16px` · radius `8px` · weight `500`_ **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** 2 · **cta** 2 · **auth** 1 · **product** 20 · **pricing** 1 · **docs** 1 · **social** 11 · **legal** 4 · **footer** 9 · **other** 9 **Primary actions (conversion path):** - Account access — "SIGN IN" (login/signup) → `https://sentry.io/auth/login/` - Primary call-to-action — "GET STARTED" (the conversion path) → `https://sentry.io/signup/` - Primary call-to-action — "TRY SENTRY FOR FREE" (the conversion path) → `https://sentry.io/signup/` **Signals:** 7/60 links carry a featured image · dominant link roles: footer-link (29), inline-link (12), content-card (9). --- ## Extraction Completeness: 73/100 (C) | Category | Score | Max | Detail | |----------|-------|-----|--------| | Colors & Palette | 25 | 25 | 23 named colors | | Typography | 20 | 20 | 9 roles defined | | Components | 8 | 20 | 2 specs extracted | | Motion & Interaction | 12 | 15 | Keyframes | | CSS Custom Properties | 3 | 10 | 64 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 (Rubik, Dammit Sans)** — 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 | |----------|----------------|-------------------| | **Dark mode** | Dark surface is the canonical medium; no separate light-mode variables detected | The dark canvas IS the design — reproduce it as the default. Do not generate a light-mode variant unless explicitly requested | ### Per-section confidence | Section | Confidence | Reason | |---------|------------|--------| | §1 Visual Theme | High | Body bg extracted via getComputedStyle() | | §2 Colors | High | 64 CSS vars (semantic naming requires ≥20 for high) | | §3 Typography | High | 9 typography roles inferred | | §4 Components | Low | 2 component variants captured | | §7 Motion | High | Keyframes + transitions | | §8 Do's/Don'ts | High | 22 rules generated; design-decisions.json has evidence per rule | | §9 Responsive | High | 6 breakpoints detected | | §9b Photography | High | 14 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).
