# Hebbia Navbar — Section Design Reference

Schema: Design Details SECTION.md v3.2
Source: https://www.hebbia.com/
Website: Hebbia
Section ID: 4bc096e5-5f21-489a-9f8e-463c6c92f9cb
Design Details page: https://designdetails.io/sections/hebbia-com--home--navbar-4bc096e5
Status: deterministic evidence partially 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

captured layout

## Visual signature

editorial, corporate, minimal, photographic, dark-mode-premium treatment at 1440×64px. The crop spans 0–64px of a 8961px page.

## Components

- Navigation Bar
- Hero
- Logo Strip
- Product UI
- Testimonial Card
- Stat Block
- Feature Collection
- Footer
- Primary Button
- Scroll Linked UI Mockup

## 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: captured layout
- Layout: captured layout
- Styles: editorial, corporate, minimal, photographic, dark-mode-premium
- Components: Navigation Bar, Hero, Logo Strip, Product UI, Testimonial Card, Stat Block, Feature Collection, Footer, Primary Button, Scroll Linked UI Mockup
- Purpose: navbar section from the Home page of Hebbia.
- Visual signature: Captured visual surface with captured layout. Inspect the crop for image and content hierarchy.
- Place on the page: 1 of 11, before Hero (`hebbia-com:home_hero`)

### Crop and composition

- Crop: 1440×64px; aspect ratio 22.5:1
- Page bounds: 0–64px of 8961px
- 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": [],
  "siteRoles": [
    {
      "role": "display",
      "size": "73.2px",
      "family": "Edict Display",
      "source": "computed",
      "traits": "uppercase",
      "weight": "390",
      "evidence": "font-1: computed CSS at 1440×1000; AI role: 73.2px 'Edict Display' serif used for the primary 'INSTITUTIONAL INTELLIGENCE' hero statement.",
      "sampleId": "font-1",
      "confidence": 1,
      "lineHeight": "65.9px",
      "letterSpacing": "1.8px"
    },
    {
      "role": "heading",
      "size": "45.4px",
      "family": "Edict Display Variable Roman",
      "source": "computed",
      "traits": "Regular",
      "weight": "400",
      "evidence": "font-2: computed CSS at 1440×1000; AI role: 45.4px 'Edict Display Variable Roman' used for section headers like 'Your firm’s knowledge at work'.",
      "sampleId": "font-2",
      "confidence": 1,
      "lineHeight": "50px",
      "letterSpacing": "0.5px"
    },
    {
      "role": "body",
      "size": "15px",
      "family": "Selecta",
      "source": "computed",
      "traits": "Regular",
      "weight": "400",
      "evidence": "font-4: computed CSS at 1440×1000; AI role: 15px 'Selecta' sans-serif used for standard descriptive text within UI components.",
      "sampleId": "font-4",
      "confidence": 0.95,
      "lineHeight": "18.8px",
      "letterSpacing": "normal"
    }
  ]
}
```

### Exact color evidence

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

```json
{
  "sectionUsage": [],
  "functionalPalette": [
    {
      "hex": "#000000",
      "name": "canvas",
      "role": "canvas",
      "source": "computed",
      "evidence": "color-2: computed rgb(0, 0, 0); AI role: Deep black (#000000) used as the primary background color across most of the page sections.",
      "sampleId": "color-2",
      "confidence": 1
    },
    {
      "hex": "#FFFFFF",
      "name": "text",
      "role": "text",
      "source": "computed",
      "evidence": "color-3: computed rgb(255, 255, 255); AI role: White (#FFFFFF) used for primary typography against the dark canvas for high contrast.",
      "sampleId": "color-3",
      "confidence": 1
    },
    {
      "hex": "#465BFF",
      "name": "primary action",
      "role": "primary-action",
      "source": "computed",
      "evidence": "color-22: computed rgb(70, 91, 255); AI role: Vibrant blue (#465BFF) used for key call-to-action buttons like 'Request a demo'.",
      "sampleId": "color-22",
      "confidence": 1
    },
    {
      "hex": "#E5E5E5",
      "name": "border",
      "role": "border",
      "source": "computed",
      "evidence": "color-10: computed rgb(229, 229, 229); AI role: Light gray (#E5E5E5) used for borders within the intricate product UI mockups (e.g., tables).",
      "sampleId": "color-10",
      "confidence": 0.95
    },
    {
      "hex": "#868686",
      "name": "muted text",
      "role": "muted-text",
      "source": "computed",
      "evidence": "color-18: computed rgb(134, 134, 134); AI role: Gray (#868686) used for secondary text details and subtext within mockups.",
      "sampleId": "color-18",
      "confidence": 0.9
    }
  ]
}
```

### Design tokens

```json
{
  "radius": "Small to medium border radii (likely 4px-8px for small elements, 12px-16px for larger cards).",
  "density": "Varies significantly; highly spacious in editorial marketing sections, but high density within the specialized product UI 'Matrix' sections.",
  "evidence": "Observed via CSS rendering of UI cards (#E5E5E5 borders), spacing around the 'Institutional Intelligence' heading, and the styling of the 'Request a demo' buttons.",
  "borderStyle": "Thin (1px), solid borders used extensively within the product interface illustrations to delineate table rows and structural bounds.",
  "buttonStyle": "Solid color fills (white or vibrant blue) with rounded corners and distinct padding.",
  "cornerStyle": "Subtly rounded corners applied consistently to buttons, UI mockups, and image containers, softening the strict geometric layout.",
  "contentWidth": "Centered content container for main text blocks, while UI mockups and images often stretch wider or utilize multi-column grids.",
  "spacingRhythm": "Generous vertical spacing between major sections, contrasting with tighter, denser spacing within UI mockups and data tables."
}
```

### Reconstruction specification

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

- Root container was not deterministically isolated.
- Layout containers: 0; cards/surfaces: 0; media elements: 0; browser animations: 0.

#### Container, grid, and spacing

```json
{
  "viewport": {
    "width": null,
    "captureBounds": null
  },
  "container": null,
  "spacing": {
    "observedGapsPx": [],
    "representativeContentWidthsPx": []
  },
  "columns": []
}
```

#### Cards and surfaces

```json
{
  "cards": [],
  "surfaces": null
}
```

#### Media treatment

```json
[]
```

#### Browser-exposed animation parameters

```json
[]
```

### 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.

```json
null
```

### 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: unknownpx 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: 5/7
- Can build: Yes
- Missing facts: section-specific computed typography and color samples; section-level geometry, surfaces, media treatment, and animation parameters; timestamped authored motion
- Warning: Buildable with adaptations for these unsupported facts: section-specific computed typography and color samples; section-level geometry, surfaces, media treatment, and animation parameters; timestamped authored motion.

### Agent implementation prompt

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

Purpose: navbar section from the Home page of Hebbia.

Structure: captured layout. Source layout label: captured layout. Preserve the documented hierarchy and relationships; exact measurements were not deterministically captured.

Visual signature to preserve at the pattern level: Captured visual surface with captured layout. Inspect the crop for image and content hierarchy.

Components: Navigation Bar, Hero, Logo Strip, Product UI, Testimonial Card, Stat Block, Feature Collection, Footer, Primary Button, Scroll Linked UI Mockup.

Style direction: editorial, corporate, minimal, photographic, dark-mode-premium.

Observed crop: 1440×64px (22.5:1). Treat this as evidence of composition, not a mandatory output size.

No section-bounded typography samples were measured.

No section-bounded color samples were measured.

No saved element-map measurements were available; do not invent exact source spacing, card, media, or animation values.

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.
