# Neko Health Navbar — Section Design Reference

Schema: Design Details SECTION.md v3.2
Source: https://www.nekohealth.com/us/en
Website: Neko Health
Section ID: 2a212e33-421f-4557-932e-8839dbc34875
Design Details page: https://designdetails.io/sections/nekohealth-com--home--navbar-2a212e33
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

1360×104px root; grid; 438.047px 435.906px 438.047px

## Visual signature

minimal, corporate, soft, medical-modern treatment at 1440×160px. The crop spans 0–160px of a 13830px page.

## Components

- Announcement Bar
- Navigation Bar
- Hero With Background Imagery
- Primary Button
- Feature Collection
- Icon Button
- Testimonial Card
- FAQ Accordion
- Footer
- Language Switcher
- Sticky Split Content
- Animated Tab Navigation

## 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: grid
- Layout: 1360×104px root; grid; 438.047px 435.906px 438.047px
- Styles: minimal, corporate, soft, medical-modern
- Components: Announcement Bar, Navigation Bar, Hero With Background Imagery, Primary Button, Feature Collection, Icon Button, Testimonial Card, FAQ Accordion, Footer, Language Switcher, Sticky Split Content, Animated Tab Navigation
- Purpose: navbar section from the Home page of Neko Health.
- Visual signature: rgba(0, 0, 0, 0) with 1360×104px root; grid; 438.047px 435.906px 438.047px. Inspect the crop for image and content hierarchy.
- Place on the page: 1 of 14, before Hero (`nekohealth-com:interactive-3d-hero`)

### Crop and composition

- Crop: 1440×160px; aspect ratio 9:1
- Page bounds: 0–160px of 13830px
- Guidance: Keep a clear anchor card and consistent internal card rules so the grid reads as one system.

### 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": "Large radius on primary buttons (pill shape), moderate-to-large radius on image containers and cards.",
  "density": "Low density; elements are widely spaced, favoring large typography and imagery over tight data clustering.",
  "evidence": "Visual inspection of button shapes, container corners, and spacing in the provided desktop crops.",
  "borderStyle": "Mostly borderless design, relying on subtle background color shifts for separation. Light borders used primarily on list items like FAQs.",
  "buttonStyle": "Primary buttons are pill-shaped with bold cyan fill. Secondary actions use small, dark, heavily rounded square icon buttons.",
  "cornerStyle": "Consistent use of large, smooth corner radii (squircle-like) on almost all container elements, images, and buttons.",
  "contentWidth": "Content is frequently centered in a readable column, while major media assets span wider or full bleed before being constrained by layout wrappers.",
  "spacingRhythm": "Very spacious vertical rhythm with large paddings between major sections, allowing content to breathe."
}
```

### Reconstruction specification

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

- Root: 1360×104px; grid; padding {"top":"0px","right":"0px","bottom":"0px","left":"0px"}; gap 24px; background rgba(0, 0, 0, 0); radius 0px.
- Observed gaps: 16, 24, 48px.
- Representative content widths: 1360, 436px.
- Layout containers: 2; cards/surfaces: 0; media elements: 2; browser animations: 0.

### 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 “Neko Health Navbar”.

Purpose: navbar section from the Home page of Neko Health.

Structure: grid. Source layout label: 1360×104px root; grid; 438.047px 435.906px 438.047px. Keep a clear anchor card and consistent internal card rules so the grid reads as one system.

Visual signature to preserve at the pattern level: rgba(0, 0, 0, 0) with 1360×104px root; grid; 438.047px 435.906px 438.047px. Inspect the crop for image and content hierarchy.

Components: Announcement Bar, Navigation Bar, Hero With Background Imagery, Primary Button, Feature Collection, Icon Button, Testimonial Card, FAQ Accordion, Footer, Language Switcher, Sticky Split Content, Animated Tab Navigation.

Style direction: minimal, corporate, soft, medical-modern.

Observed crop: 1440×160px (9:1). Treat this as evidence of composition, not a mandatory output size.

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.
