Status: deterministic evidence captured; editorial AI review pending

## Purpose

This is a footer section on the Home page. Use the attached crop and measured browser facts to reconstruct its composition. Do not infer unmeasured source values.

## Layout

1440×643px root; block

## Visual signature

minimal, corporate, geometric, product-led, tech-forward treatment at 1440×643px. The crop spans 13361–14004px of a 14004px page.

## Components

- Announcement Bar
- Navigation Bar
- Hero
- Product UI
- Logo Strip
- Stat Block
- Feature Collection
- Testimonial Card
- Footer
- Primary Button
- Outline Button
- UI Mockup Grid
- Feature Bento Box

## Evidence note

The geometry, typography, colors, media, and animation parameters below come from saved HTML/CSS/browser evidence when present. Website-level roles are supplied separately. Editorial section judgment remains pending unless the MCP resolves this source ID to a promoted canonical record.

## Build blueprint v3.2

### Purpose and classification

- Canonical type: footer
- Source type: footer
- Structure: 1440×643px root; block
- Layout: 1440×643px root; block
- Styles: minimal, corporate, geometric, product-led, tech-forward
- Components: Announcement Bar, Navigation Bar, Hero, Product UI, Logo Strip, Stat Block, Feature Collection, Testimonial Card, Footer, Primary Button, Outline Button, UI Mockup Grid, Feature Bento Box
- Purpose: footer section from the Home page of Gumloop: Build AI agents for work.
- Visual signature: rgb(255, 255, 255) with 1440×643px root; block. Inspect the crop for image and content hierarchy.
- Place on the page: 14 of 14, after Call to action (`1a3bb148-8a93-4c82-914c-ee6e91aba397`)

### Crop and composition

- Crop: 1440×643px; aspect ratio 2.24:1
- Page bounds: 13361–14004px of 14004px
- Guidance: Preserve the documented hierarchy and relationships; exact measurements were not deterministically captured.

### Exact typography evidence

The sectionScale values were measured inside this crop. The siteRoles values explain how those faces function across the source website; they must not replace section measurements.

### Exact color evidence

The section samples record where each computed value was used. Functional roles come from the website-level classifier and remain separate.

### Design tokens

```json
{
  "radius": "Small to medium. UI elements within mockups use small radii, while larger containers might use slightly larger radii (e.g., 12px) for containment.",
  "density": "Low. The design favors clarity and focus over information density. Large text sizes, ample whitespace, and focused UI mockups create a spacious, uncluttered feel.",
  "evidence": "Visual inspection of the screenshots confirms large gaps between the 'Hero', 'Let your experts...', and 'A real browser...' sections. The borders on the 'Trusted connections' and 'A password vault' cards are thin and light. Buttons like 'Get Started' and 'Book a demo' show the distinct solid/outline styles.",
  "borderStyle": "Subtle and thin. Borders (like #EBEBF1) are used extensively to define cards, inputs, and structure within mockups, typically 1px solid.",
  "buttonStyle": "Solid and Outline. Primary buttons are solid black with white text; secondary buttons are white with subtle gray borders. Both feature modest padding and slightly rounded corners.",
  "cornerStyle": "Slightly rounded. Most cards, buttons, and UI mockup containers use a small border-radius (likely 4px to 8px), softening the geometric layout.",
  "contentWidth": "Wide, but contained. The main content appears to follow a maximum width constraint (likely around 1200px-1440px), centering the layouts on wider screens.",
  "spacingRhythm": "Generous spacing. Large vertical margins (likely 120px+) separate major sections, giving the content room to breathe and emphasizing the blocky structure."
}
```

### Reconstruction specification

This is the implementation contract for the captured desktop viewport. Prefer section-specific facts here over general website descriptions.

- Root: 1440×643px; block; padding {"top":"40px","right":"0px","bottom":"40px","left":"0px"}; gap normal; background rgb(255, 255, 255); radius 0px.
- Observed gaps: 8px.
- Layout containers: 0; cards/surfaces: 0; media elements: 1; browser animations: 0.

### Measured geometry, surfaces, media, and animation

These raw values come from the saved element map and computed styles. Empty arrays mean the fact was not captured; they are not permission to invent source values.

### Observed motion

No timestamped authored motion is attached. Use only restrained baseline transitions.

The browser animation records above are deterministic parameters captured from active browser animations. The timestamped observations describe what Gemini saw in the video. Treat them as complementary evidence. When either source is empty or they conflict, state the uncertainty instead of inventing timing or easing.

### Responsive contract

- Measured viewport: 1440px wide.
- Mobile/tablet values: not measured by this section evidence unless a separate capture is explicitly listed.
- Preserve hierarchy and sequence; collapse simultaneous columns only where needed, maintain media aspect ratios, and verify touch targets and text wrapping at target breakpoints.

### Structure versus visual skin

- Preserve: content hierarchy, layout relationships, section rhythm, interaction purpose.
- Adapt: brand colors, font family, copy, imagery, icons, decorative details.
- Rule: Preserve the observed design logic while creating original branding, copy, assets, and implementation details.

### Adaptation and dependencies

- Effort: Not assessed
- What transfers: Documented hierarchy and composition
- Dependencies: None recorded
- Guidance: Adapt the pattern to the new product and content.

### Evidence readiness

- Coverage: 6/7
- Can build: Yes
- Missing facts: section-specific computed typography and color samples; timestamped authored motion
- Warning: Buildable with adaptations for these unsupported facts: section-specific computed typography and color samples; timestamped authored motion.

### Agent implementation prompt

Create an original footer section inspired by the design evidence titled “Multi-column link footer”.

Purpose: footer section from the Home page of Gumloop: Build AI agents for work.

Structure: 1440×643px root; block. Source layout label: 1440×643px root; block. Preserve the documented hierarchy and relationships; exact measurements were not deterministically captured.

Visual signature to preserve at the pattern level: rgb(255, 255, 255) with 1440×643px root; block. Inspect the crop for image and content hierarchy.

Components: Announcement Bar, Navigation Bar, Hero, Product UI, Logo Strip, Stat Block, Feature Collection, Testimonial Card, Footer, Primary Button, Outline Button, UI Mockup Grid, Feature Bento Box.

Style direction: minimal, corporate, geometric, product-led, tech-forward.

Observed crop: 1440×643px (2.24:1). Treat this as evidence of composition, not a mandatory output size.

No section-bounded typography samples were measured.

Do not invent signature motion. Use only restrained baseline transitions if the product needs them.

Transfer the documented hierarchy and composition rather than source copy or assets.

No explicit dependencies were recorded.

Adapt the pattern to the new product and content.

Use new copy, imagery, branding, and implementation details. Do not reproduce the source website or its proprietary assets.
