# Cogent Navbar — Section Design Reference

Schema: Design Details SECTION.md v3.2
Source: https://www.cogent.com/
Website: Cogent
Section ID: 2443cf66-8b90-46db-9954-4a41060aca2e
Design Details page: https://designdetails.io/sections/cogent-com--home--navbar-2443cf66
Status: deterministic evidence captured; editorial AI review pending

## Purpose

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

## Layout

1440×52px root; flex

## Visual signature

gradient, typographic, minimal, corporate, cyber-technical, dark-mode-native treatment at 1440×52px. The crop spans 0–52px of a 17201px page.

## Components

- Navigation Bar
- Hero
- Feature Card
- Stat Block
- Logo Strip
- Editorial Card
- Video Frame
- Newsletter Form
- Primary Button
- Footer
- Pixelated Display Typography
- Simulated UI Widgets
- Translucent Surfaces

## 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: navigation
- Source type: navbar
- Structure: 1440×52px root; flex
- Layout: 1440×52px root; flex
- Styles: gradient, typographic, minimal, corporate, cyber-technical, dark-mode-native
- Components: Navigation Bar, Hero, Feature Card, Stat Block, Logo Strip, Editorial Card, Video Frame, Newsletter Form, Primary Button, Footer, Pixelated Display Typography, Simulated UI Widgets, Translucent Surfaces
- Purpose: navbar section from the Home page of Cogent.
- Visual signature: rgb(248, 248, 248) with 1440×52px root; flex. Inspect the crop for image and content hierarchy.
- Place on the page: 1 of 16, before Hero (`cogent-com:C01`)

### Crop and composition

- Crop: 1440×52px; aspect ratio 27.692:1
- Page bounds: 0–52px 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.

### 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": "Medium border-radius (likely 8-12px) on buttons and input fields; slightly larger on feature cards.",
  "density": "Spacious. The design relies on large negative space to let the typography and glowing gradients breathe.",
  "evidence": "Observed via screenshot layouts, button shapes in the nav and hero, padding around text blocks, and the containment of elements across different viewport heights.",
  "borderStyle": "Subtle, low-opacity 1px solid borders used to define cards against the dark background without adding visual noise.",
  "buttonStyle": "Primary buttons are solid, high-contrast (white background, black text). Secondary buttons use translucent dark fills with subtle borders.",
  "cornerStyle": "Rounded corners on interactive elements and structural cards, contrasting with the pixelated typography.",
  "contentWidth": "Centered max-width container, likely around 1200px to 1440px for primary content areas.",
  "spacingRhythm": "Generous vertical spacing between major sections (often 120px+). Internal card padding is tight but structured."
}
```

### Reconstruction specification

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

- Root: 1440×52px; flex; padding {"top":"0px","right":"0px","bottom":"0px","left":"0px"}; gap 10px; background rgb(248, 248, 248); radius 0px.
- Observed gaps: 8, 10px.
- Layout containers: 2; cards/surfaces: 0; media elements: 0; browser animations: 0.

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: 7/7
- Can build: Yes
- Missing facts: timestamped authored motion
- Warning: Buildable with adaptations for these unsupported facts: timestamped authored motion.

### Agent implementation prompt

Create an original navigation section inspired by the design evidence titled “Cogent Navbar”.

Purpose: navbar section from the Home page of Cogent.

Structure: 1440×52px root; flex. Source layout label: 1440×52px root; flex. Preserve the documented hierarchy and relationships; exact measurements were not deterministically captured.

Visual signature to preserve at the pattern level: rgb(248, 248, 248) with 1440×52px root; flex. Inspect the crop for image and content hierarchy.

Components: Navigation Bar, Hero, Feature Card, Stat Block, Logo Strip, Editorial Card, Video Frame, Newsletter Form, Primary Button, Footer, Pixelated Display Typography, Simulated UI Widgets, Translucent Surfaces.

Style direction: gradient, typographic, minimal, corporate, cyber-technical, dark-mode-native.

Observed crop: 1440×52px (27.692:1). Treat this as evidence of composition, not a mandatory output size.
