Interaction State Narrative

  • **Button**:
  • - **focus:** bg transparent → rgba(255, 255, 255, 0.075), text #8a8f98 → #f3f4f5, border changes
  • **FooterLink**:
  • - **hover:** text #f7f8f8 → #dfe1e3, border changes
Agent usage: Validate generated components against this matrix. If your output's `:hover` state changes properties not listed here, you are off-brand.

    description: "Dark-canvas product system built on #08090a with #5e6ad2 as the single brand accent. Type anchored in Inter Variable at 64px / weight 510. Extracted automatically from https://linear.app/ — every value from getComputedStyle(), no approximation."
    narrative: |
      linear.app is built on a near-black canvas (rgb(8, 9, 10)).
      The system uses #5e6ad2 as the accent for primary actions and brand signals.
      Fully-rounded CTAs (9999px) signal a friendly, tactile interaction model alongside Inter Variable as the primary typeface.

    > **🤖 TL;DR for AI agents** (read this first — saves you scanning the full doc):
    >
    > - **Canvas**: `rgb(8, 9, 10)` is the page background. Every component composits against this.
    > - **Accent**: `#5e6ad2` for primary CTAs ONLY. Never decorative.
    > - **Body type**: 16px (token: `typography.body`). Default for ALL text not in a heading role.
    > - **Section rhythm**: 72px between major bands. Card padding: 24px.

    ## 1. Visual Theme & Atmosphere
    
    linear.app commits fully to dark-mode as the native medium, not as a toggled alternative. The canvas is an inky black surface (`#08090a`) 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 **Inter Variable**, deployed with OpenType features enabled globally (`"cv01", "ss03"`). These aren't decorative — they're load-bearing: without them, the typeface reverts to its generic state and the design loses its specific texture. The weight scale rejects the standard 100/200/.../900 ladder in favor of custom values (max **680** in this system) — a deliberate signal that this design system is precisely tuned, not assembled from defaults. Negative letter-spacing at display sizes (-1.408px at 64px) compresses headlines into engineered blocks, dense and authoritative. 
    
    Body text reads in Off-Cream (`#f7f8f8`) (contrast ratio 28.1:1, well above WCAG AA). **Indigo** (`#5e6ad2`) 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.

    ### Typography Hierarchy
    
    | Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
    |------|------|------|--------|-------------|----------------|-------|
    | Display Hero | Inter Variable | 72px | 510 | 1 | -1.584px | Main headline (h2) |
    | Section Heading | Inter Variable | 64px | 510 | 1 | -1.408px | Section titles (h1) |
    | Sub-heading | Inter Variable | 20px | 590 | 1.33 | -0.24px | Third-level heading (h3) |

    | Link | Inter Variable | 14px | 510 | 1.5 | normal | Link (14px) — Decoration: none |
    | Input | Berkeley Mono | 14px | 400 | 1.71 | normal | Form input (14px) |

    ### Font Weight Scale
    
    CSS custom properties define 6 explicit weight steps:
    - `--font-weight-light`: `300` — Light
    - `--font-weight-normal`: `400` — Regular
    - `--dp-font-weight-medium`: `500` — Medium
    - `--font-weight-medium`: `510` — Medium (custom, ~500)
    - `--font-weight-semibold`: `590` — SemiBold (custom, ~600)
    - `--font-weight-bold`: `680` — Bold (custom, ~700)
    
    ### Full Font Size Scale
    
    Sizes detected in the design (descending): `64px`, `48px`, `32px`, `24px`, `20px`, `18px`, `17px`, `16px`, `15px`, `14px`, `13.33px`, `13px`, `12.25px`, `12px`, `11px`, `10px`
    
    > 9 size(s) detected outside the sampled hierarchy (48px, 32px, 24px, 18px, 17px, 15px, 12.25px, 11px, 10px). 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:
    
    - **stylistic sets** (`ss0X`) — alternate letterforms enabled (often for brand-specific glyph variants)
    
    **Clone instruction:** Enable these in your CSS:
    ```css
    body {
      font-feature-settings: "cv01", "ss03", "ss01";
    }
    ```

    ## 4b. Component Behaviors (State Matrix)
    
    ### Interaction State Narrative
    
    - **Button**:
      - **focus:** bg transparent → rgba(255, 255, 255, 0.075), text #8a8f98 → #f3f4f5, border changes
    - **FooterLink**:
      - **hover:** text #f7f8f8 → #dfe1e3, border changes

    |-----------|---------------|
    | Buttons | `9999px` |
    | Cards & Containers | `8px` |
    | Inputs & Forms | `6px` |
    | Navigation | `none` |
    | Code Blocks | `4px` |
    | Page Body | `0px` |
    | Primary Input | `6px` |
    
    **Shape Personality**: Sharp + Pill Contrast — Angular precision with pill-shaped accents (status badges, tags). Creates strong visual hierarchy.
    
    **Full Radius Spectrum**: 0px, 1px, 2px, 4px, 6px, 7px, 8px, 12px (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** | `32px` | Between major bands (color change, content shift) |
    | **subsection** | `24px` | Within a section, between content groups |
    | **card** | `14px` | Card padding, list-item spacing |
    | **compact** | `12px` | Form fields, tight clusters, badge padding |
    | **micro** | `6px` | 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

    - **Clone instruction:** Build a 1-column grid (desktop) with cards at ~1.87:1 aspect ratio. Each card has an image at the top.
    
    ### Testimonial Pattern
    
    - **Count:** 9 testimonial blocks
    - **Layout:** grid
    - **Avg quote length:** 154 chars (medium quote)
    - **Includes:** ✗ no avatars | ✗ no logos | ✗ no ratings

    - **Links:** 37 total
    - **Height:** 464px
    - **Includes:** ✗ no newsletter | ✓ social icons |  
    - **Clone instruction:** Build a 5-column footer with ~7 links per column, social media links.
    
    ## 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 8px 2px 0px`,<br>`rgba(0, 0, 0, 0.01) 0px 5px 2px 0px`,<br>`rgba(0, 0, 0, 0.04) 0px 3px 2px 0px`,<br>`rgba(0, 0, 0, 0.07) 0px 1px 1px 0px`,<br>`rgba(0, 0, 0, 0.08) 0px 0px 1px 0px` | Cards, elevated surfaces |
    | Layered (Level 2) | <br>`rgba(94, 106, 210, 0.008) 0px 0px 0px 9.05908px` | Cards, elevated surfaces |
    | Layered (Level 3) | <br>`rgba(0, 0, 0, 0.1) 0px 0px 0px 2px` | Cards, elevated surfaces |
    | Layered (Level 4) | <br>`rgba(0, 0, 0, 0.2) 0px 0px 0px 1px` | Cards, elevated surfaces |
    
    **Shadow Philosophy**: Multi-layered shadow system creating natural, atmospheric depth. Each shadow level combines multiple layers for realistic elevation.

    ## 8. Do's and Don'ts
    
    ### Do
    - Use dark background (`#08090a`) as the foundation — this is a dark-mode-native design
    - Use Inter Variable as the primary typeface — it defines the brand personality
    - Use weight 680 for the heaviest text — this design uses a custom heavy weight, not the standard 700 (bold)
    - Use negative letter-spacing (-1.408px) at display sizes for compressed, editorial headlines
    - 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 Indigo (`#5e6ad2`) as the primary accent — it's the brand's signature interactive color
    - Use pill-shaped radius (9999px) for primary CTA buttons — the brand uses fully-rounded, pill CTAs
    - Use 8px border-radius on cards — consistent with the grid card corners
    - Style form inputs with a `1px solid rgba(255, 255, 255, 0.08)` border — use border-based inputs, not floating labels or underline-only
    - Maintain nav height at 72px — consistent vertical space for the navigation bar
    - Make the hero full-viewport (≥70% screen height) — this design uses an immersive hero, not a tall navbar
    - Include exactly 8 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose
    - Each card includes a top image — imagery is part of the card identity, not optional
    - Lay out testimonials in a grid (9+ items) — quantity signals scale and trust
    - 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 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 substitute weight 680 with the standard 700 — the custom value is part of the brand's type personality
    - 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 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 use rectangular buttons for primary actions — the rounded pill shape is the brand standard
    - 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(8, 9, 10)` as the base canvas"
        why: "Every component is designed to composit against this exact tone"
        test: "document.body.style.backgroundColor === 'rgb(8, 9, 10)'"
      - id: brand-accent-001
        type: do
        rule: "Reserve `#5e6ad2` for primary CTAs and brand-mark signals only"
        why: "Single chromatic assertion device — overuse dilutes meaning"
        test: "querySelectorAll('[style*=\"#5e6ad2\"]').length <= 3 per fold"
    ```
    
    ## 9. Responsive Behavior
    
    ### Breakpoints
    | Name | Width | Key Changes |
    |------|-------|-------------|
    | Mobile Large | 600px | Expanded mobile layout |
    | Mobile Large | 640px | Expanded mobile layout |
    | Tablet | 768px | Multi-column grids begin |
    | Tablet | 1024px | Multi-column grids begin |
    | Desktop | 1280px | Full feature layout |
    
    ### Token Diff — Desktop vs Mobile
    
    | Element | Property | Desktop | Mobile |
    |---------|----------|---------|--------|
    | heading | font-size | `64px` | `38px` |
    | heading | line-height | `64px` | `41.8px` |
    | heading | letter-spacing | `-1.408px` | `-0.836px` |
    | nav | flex-direction | `row` | `column` |
    | button | width | `73px` | `auto` |
    
    ### Collapsing Strategy
    - Headlines: 64px → 38px 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 12px 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 CTAs:** 8 on desktop → 3 on mobile (secondary CTAs dropped on small screens).
    - **Navigation collapses to hamburger** — 5 links visible on desktop, 1 on mobile (the rest hide behind a menu toggle).
    - **Footer columns collapse:** 5 columns (desktop) → 2 columns (mobile).
    
    ## 9b. Visual Tone & Photography
    
    **Tone:** Illustration-driven
    
    The site relies primarily on illustrations, vector art, and decorative SVG elements rather than photography. Use commissioned illustrations, icon sets, or generated graphics for clones — stock photos will feel off-brand.
    
    **Canonical Brand Image (OG):**
    - https://linear.app/static/og/homepage.jpg
      *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: 1.79:1 (landscape (16:9-ish))
    - Rendered size: 1440×804px
    - *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): 2 (100%)
    - Portrait (<0.87): 0 (0%)
    - Square (0.87–1.15): 0 (0%)
    
    **Media Format Mix:**
    - SVG: 5 (icons, illustrations, decorative geometry)
    
    **Average rendered image size:** 1428×786px
    **Above-fold image count:** 2 / 2
    
    **Decorative Patterns Detected:**
    - 1 multi-stop linear gradient (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth
    - 3 radial gradients — circular color blooms used for spotlight/glow effects
    - 5 large decorative SVG shapes (≥200×200px, non-icon) — likely blob/illustration accents
    - 1 background pattern (non-photo url() backgrounds) — textures/illustrations as backdrops
    - **Glassmorphism** detected (`backdrop-filter: blur`) — layered transparent surfaces with blur, modern OS-like aesthetic
    - **Noise/grain texture** detected — adds tactile film grain to flat backgrounds
    
    **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:**
    - Use vector illustration as the primary visual language — photos will read as off-brand.
    - Maintain consistent illustration style (line weight, color palette) across the site.
    
    ## 10. Agent Prompt Guide
    
    ### Quick Reference
    - Background: Jet Black (`#08090a`)
    - Primary text: Off-Cream (`#f7f8f8`)
    - Accent: Indigo (`#5e6ad2`)
    - Border: Dim Gray (`#62666d`)
    - Font: Inter Variable
    - Body: 16px weight 400
    
    ### Example Component Prompts
    - "Create a hero section on Jet Black background (#08090a). Headline at 64px Inter Variable weight 510, line-height 1, letter-spacing -1.408px, color #f7f8f8."
    - "Create the primary CTA button: `#5e6ad2` background, `#8a8f98` text, 9999px border-radius, 0px 12px padding, 590 weight, Inter Variable font."
    - "Design a card on `#0f1011` background. Border: 1px solid rgba(255, 255, 255, 0.05). Radius: 8px. Shadow: none. Padding: 0px 24px 28px."
    - "Build navigation: static on `#08090a`. Inter Variable 16px weight 400 for links."
    
    ### Iteration Guide
    1. **Canvas**: Set the dark canvas to Jet Black (`#08090a`) — every component is composited against this exact base.
    2. **Typography**: All type in Inter Variable, weight range 300–680. Never exceed 680 — heavier weights break the brand's tonal restraint.
    3. **Accent**: Indigo (`#5e6ad2`) is the sole interactive color. On hover → Accent (`#7170ff`). Use CSS transitions, not opacity/brightness filters.
    4. **Focus**: Render focus rings in Indigo (`#5e69d1`) — never hide focus outlines. The ring color is distinct from the accent to avoid ambiguity.
    5. **Motion**: All transitions use `cubic-bezier(0.25,0.46,0.45,0.94)`. Timing: 100ms for micro-interactions, 150ms for layout changes. Never use linear for UI transitions — preserve the brand's easing personality.
    6. **Shape**: CTAs at `9999px`, cards at `8px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
    7. **Spacing**: Use the `--ca-space-*` token scale (6px–32px). All padding, margin, and gap values are multiples from this scale — no magic numbers.
    8. **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:
        - "A new species of product tool. Purpose-built for modern teams with AI workflows at its core, Linear"
        - "Make product operations self-driving"
        - "Changelog"
        - "Built for the future. Available today."
      sub-headings:
        - "Faster app launch"
        - "Product"
      ctas:
        - "Product"
        - "Linear"
        - "Inbox"
        - "Workspace"
        - "Faster app launch"
      navigation:
        - "Customers"
        - "Pricing"
        - "Now"
        - "Contact"
        - "Docs"
        - "Open app"
        - "Log in"
        - "Sign up"
      footer-links:
        - "Intake"
        - "Privacy"
    ```
    
    **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: 1.84
        common-aspect: "~16:9 landscape"
      thumbnail:
        count: 24
        avg-ratio: 1.00
        common-aspect: "~1:1 square"
        sample-alts:
          - "Avatar of Karri"
          - "Avatar of Karri"
    ```
    
    **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">
      Product
    </button>
    ```
    _Source pattern detected: padding `0px 12px` · radius `9999px` · weight `400`_
    
    **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:*
    
    - **1 parasitic shadow(s) detected** — colored box-shadows (not near-black) found in allShadows. These likely originate from browser extensions or third-party injected widgets (e.g. Grammarly, chat overlays), not from the site's own design system. Discard them when building.

    ## 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 | 630 CSS vars (semantic naming requires ≥20 for high) |
    | §3 Typography | High | 12 typography roles inferred |
    | §4 Components | High | 5 component variants captured |
    | §7 Motion | High | Keyframes + transitions |
    | §8 Do's/Don'ts | High | 27 rules generated; design-decisions.json has evidence per rule |
    | §9 Responsive | High | 5 breakpoints detected |
    | §9b Photography | High | 2 images, hero present |
