description: "Dark-canvas product system built on #1f1633 with #6a5fc1 as the single brand accent. Type anchored in Rubik at 88px / weight 700. Extracted automatically from https://sentry.io/ — every value from getComputedStyle(), no approximation."
narrative: |
  sentry.io is built on a near-black canvas (rgb(31, 22, 51)).
  The system uses rgb(106, 95, 193) as the accent for primary actions and brand signals.
  Moderately rounded CTAs (8px) — modern SaaS standard, neither sharp nor pill alongside Rubik as the primary typeface.

# Design System — sentry.io
> Extracted automatically by Clone Architect from https://sentry.io
> Date: 2026-05-30
> Viewport: Desktop 1440x900 + Mobile 390x844
> Every value in this file comes from real getComputedStyle() — no approximation.

> **🤖 TL;DR for AI agents** (read this first — saves you scanning the full doc):
>
> - **Canvas**: `rgb(31, 22, 51)` is the page background. Every component composits against this.
> - **Accent**: `rgb(106, 95, 193)` for primary CTAs ONLY. Never decorative.
> - **Body type**: 16px (token: `typography.body`). Default for ALL text not in a heading role.
> - **Section rhythm**: 48px between major bands. Card padding: 24px.
> - **Default radius**: 8px on buttons/inputs. Pills (`9999px`) only for icon-buttons or status chips.
>
> **Before generating UI**: import this DESIGN.md, scan §2 (Color Palette) + §4 (Components) + §10 (Agent Guide). 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. 

Typography is anchored in **Rubik**. Headlines use weight 700 for confident, assertive presence — the brand wants to be heard. 

Body text reads in Pure White (`#ffffff`). **Slate Blue** (`#6a5fc1`) provides interactive distinction without visual aggression. Elevation is built from multi-layer shadow stacks — each level combines several blurred layers at varying offsets to simulate the way light actually falls on stacked surfaces, not the simulated drop-shadow of cheap interfaces. 
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: Light Gray (`#e5e7eb`)
- Accent: Slate Blue (`#6a5fc1`)
- Display: 88px weight 700
- Shadow system: 6 distinct elevation levels
- Custom fonts loaded: Rubik, Dammit Sans

    hover:
      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.*

- **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

### Navigation
- **1 shape(s)** in this system: `Main Nav`
- **DO NOT introduce new navigation variants** without justification

### Code Blocks
- **1 shape(s)** in this system: `Inline Code / Pre`
- **DO NOT introduce new code blocks 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 | 34.848px |
| 2xl | 48px |
| 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 | 18px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `8px` |
| Inputs & Forms | `6px` |
| Navigation | `none` |
| Code Blocks | `0px` |
| Page Body | `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

*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** | `34.848px` | 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. No imagery needed for hero — text-driven.

### 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) | <br>`rgba(0, 0, 0, 0) 0px 0px 0px 0px`,<br>`rgba(0, 0, 0, 0) 0px 0px 0px 0px`,<br>`rgba(0, 0, 0, 0.1) 0px 10px 15px -3px`,<br>`rgba(0, 0, 0, 0.1) 0px 4px 6px -4px` | Cards, elevated surfaces |
| Layered (Level 2) | <br>`rgba(0, 0, 0, 0.08) 0px 2px 8px 0px` | Cards, elevated surfaces |
| Inset (Level 3) | <br>`rgba(0, 0, 0, 0.1) 0px 1px 3px 0px inset` | Buttons, pressed-state elements |
| Layered (Level 4) | <br>`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

> 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 Blue (`#6a5fc1`) 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–34.848px spacing range — the design uses a wide scale for visual breathing room
- Keep the hero centered and text-driven — no decorative media, typography carries the message
- 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 add hero illustrations or photos — they'll break the typographic restraint
- 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(106, 95, 193)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(106, 95, 193)\"]').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).

## 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:**
- 33 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 Blue (`#6a5fc1`)
- Border: Slate Gray (`#79628c`)
- 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: `#6a5fc1` 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 Blue (`#6a5fc1`) is the sole interactive color. On hover → Hot Pink (`#fa7faa`). 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–35px). 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.

**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:
    - "Error Monitoring"
    - "Logs"
    - "Seer
NEW"
    - "Agent
NEW"
    - "Autofix
NEW"
    - "AI Code Review
NEW"
    - "Session Replay"
    - "Metrics
NEW"
    - "Tracing"
    - "Profiling"
  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
<button class="btn btn-primary">
  PLATFORM
</button>
```
_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.


## 12. Known Extraction Gaps

*Auto-detected limitations of this extraction — understand before building:*

- **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.

## 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.

| Category | What's missing | Fallback strategy |
|----------|----------------|-------------------|
| **Dark mode** | No dark-mode CSS variables or media queries detected | Light mode is canonical; do not generate dark-mode variants 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 | Medium | 4 component variants captured |
| §7 Motion | High | Keyframes + transitions |
| §8 Do's/Don'ts | High | 24 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | High | 6 breakpoints detected |
| §9b Photography | High | 14 images, hero present |
