# Subscribe to updates — Section Design Reference

Schema: Design Details SECTION.md v3.2
Source: https://www.cogent.com/
Website: Cogent
Section ID: 42dafd18-53ab-45ab-bb72-47798a32ca0f
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

1440×802px root; flex

## Visual signature

Visual treatment is preserved in the crop. at 1440×802px. The crop spans 16399–17201px of a 17201px page.

## Components

- Hero
- Feature collection
- Footer

## 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: 1440×802px root; flex
- Layout: 1440×802px root; flex
- Styles: Not identified
- Components: Hero, Feature collection, Footer
- Purpose: footer section from the Home page of Cogent.
- Visual signature: rgba(0, 0, 0, 0) with 1440×802px root; flex. Inspect the crop for image and content hierarchy.

### Crop and composition

- Crop: 1440×802px; aspect ratio 1.796:1
- Page bounds: 16399–17201px of 17201px
- 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.

```json
{
  "sectionScale": [
    {
      "role": "section heading",
      "family": "Geist",

}
```

### Exact color evidence

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

### Reconstruction specification

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

- Root: 1440×802px; flex; padding {"top":"0px","right":"0px","bottom":"0px","left":"0px"}; gap 0px; background rgba(0, 0, 0, 0); radius 0px.
- Observed gaps: 5, 8px.
- Representative content widths: 924, 460, 323, 256px.
- Layout containers: 1; cards/surfaces: 0; media elements: 6; browser animations: 0.

#### Browser-exposed animation parameters

### 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: 4/7
- Can build: Yes
- Missing facts: exact typography roles and computed values; functional color roles and exact values; spacing, radius, shadow, and breakpoint tokens; timestamped authored motion
- Warning: Buildable with adaptations for these unsupported facts: exact typography roles and computed values; functional color roles and exact values; spacing, radius, shadow, and breakpoint tokens; timestamped authored motion.

### Agent implementation prompt

Create an original footer section inspired by the design evidence titled “Subscribe to updates”.

Purpose: footer section from the Home page of Cogent.

Structure: 1440×802px root; flex. Source layout label: 1440×802px root; flex. Preserve the documented hierarchy and relationships; exact measurements were not deterministically captured.

Visual signature to preserve at the pattern level: rgba(0, 0, 0, 0) with 1440×802px root; flex. Inspect the crop for image and content hierarchy.

Components: Hero, Feature collection, Footer.

Style direction: No style labels supplied.

Observed crop: 1440×802px (1.796:1). Treat this as evidence of composition, not a mandatory output size.

Typography values are unsupported; choose an appropriate type system and label it as an adaptation.

Exact color values are unsupported; derive an original functional palette from the visual crop and label it as an adaptation.
