# Biotic Navbar — Section Design Reference

Schema: Design Details SECTION.md v3.2
Source: https://biotic.org/
Website: Biotic
Section ID: e162dbf2-1609-43b4-83b0-211ecb828607
Design Details page: https://designdetails.io/sections/biotic-org--home--navbar-e162dbf2
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

1440×90px root; grid; 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px

## Visual signature

minimal, typographic, corporate, generative, high-contrast treatment at 1440×90px. The crop spans 0–90px of a 8222px page.

## Components

- Navigation Bar
- Hero
- Feature Collection
- Newsletter Form
- Primary Button
- Footer
- Generative Background
- Countdown Tracker
- Dotted Dividers

## 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: 1440×90px root; grid; 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px
- Styles: minimal, typographic, corporate, generative, high-contrast
- Components: Navigation Bar, Hero, Feature Collection, Newsletter Form, Primary Button, Footer, Generative Background, Countdown Tracker, Dotted Dividers
- Purpose: navbar section from the Home page of Biotic.
- Visual signature: rgba(0, 0, 0, 0) with 1440×90px root; grid; 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px. Inspect the crop for image and content hierarchy.
- Place on the page: 1 of 10, before Hero (`deb008a2-9873-4ac6-904b-ee760960f79f`)

### Crop and composition

- Crop: 1440×90px; aspect ratio 16:1
- Page bounds: 0–90px of 8222px
- 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": "Pill-shaped radii for form fields and primary action buttons.",
  "density": "Low density; the design leverages substantial whitespace to emphasize typography and large generative graphics.",
  "evidence": "Visible in component layout, button shapes, and the strict adherence to dotted line separators across distinct background colors.",
  "borderStyle": "Distinctive use of fine dotted horizontal lines (1px) as dividers between content rows.",
  "buttonStyle": "Solid fill pill buttons, often utilizing the bright accent color for high visibility.",

}
```

### Reconstruction specification

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

- Observed gaps: 15px.
- Representative content widths: 447px.
- Layout containers: 2; cards/surfaces: 0; media elements: 1; 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 “Biotic Navbar”.

Purpose: navbar section from the Home page of Biotic.

Structure: grid. Source layout label: 1440×90px root; grid; 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px. 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 1440×90px root; grid; 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px 100.406px. Inspect the crop for image and content hierarchy.

Components: Navigation Bar, Hero, Feature Collection, Newsletter Form, Primary Button, Footer, Generative Background, Countdown Tracker, Dotted Dividers.

Style direction: minimal, typographic, corporate, generative, high-contrast.

Observed crop: 1440×90px (16:1). Treat this as evidence of composition, not a mandatory output size.

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.
