# bleibtgleich'26 Navbar — Section Design Reference

Schema: Design Details SECTION.md v3.2
Source: https://bleibtgleich.dev/
Website: bleibtgleich'26
Section ID: 837a12d2-aa6f-4fb5-9165-5c8666a30794
Design Details page: https://designdetails.io/sections/bleibtgleich-dev--home--navbar-837a12d2
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

1440×39px root; block

## Visual signature

minimal, typographic, bold, brutalist, monochromatic, structural treatment at 1440×39px. The crop spans 0–39px of a 6679px page.

## Components

- Navigation Bar
- Hero
- Carousel
- Icon Button
- Footer
- Fixed Corner Branding
- Interactive Media Mask
- Structural Alignment Lines

## 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: 1440×39px root; block
- Layout: 1440×39px root; block
- Styles: minimal, typographic, bold, brutalist, monochromatic, structural
- Components: Navigation Bar, Hero, Carousel, Icon Button, Footer, Fixed Corner Branding, Interactive Media Mask, Structural Alignment Lines
- Purpose: navbar section from the Home page of bleibtgleich'26.
- Visual signature: rgba(0, 0, 0, 0) with 1440×39px root; block. Inspect the crop for image and content hierarchy.
- Place on the page: 1 of 5, before Hero (`0a75c684-7987-4e05-841d-71fca2065a9d`)

### Crop and composition

- Crop: 1440×39px; aspect ratio 36.923:1
- Page bounds: 0–39px of 6679px
- 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": "UI/supporting text",
      "family": "Akzidenz Grotesk Pro",

      "lineHeight": "15px",
      "letterSpacing": "-0.4px"
    }
  ]
}
```

### 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": [
    {
      "value": "#FFFFFF",
      "cssValue": "rgb(255, 255, 255)",

      "appliedAs": [
        "background",
        "text",
        "border"
      ],
      "occurrences": 14,
      "sourceId": "color-1"
    },
    {
      "value": "#F2F2F2",

      "sampleId": "color-3",
      "confidence": 1
    }
  ]
}
```

### Design tokens

```json
{
  "radius": "0px for general layout blocks; 50% for icon buttons and the pill-shaped menu button.",
  "density": "Extremely low density; the design prioritizes vast amounts of negative space to emphasize individual typographic elements.",
  "evidence": "Observed from large typography (font-2 at 90px), circular buttons near the footer, thin vertical lines intersecting content, and overall layout crops showing widespread blank areas.",
  "borderStyle": "1px solid black lines used primarily as structural or alignment guides, as well as outlining circular buttons.",
  "buttonStyle": "Minimalist outlined style: transparent backgrounds with thin black borders and centered black text or icons.",
  "cornerStyle": "Contrasting corner styles: completely sharp 0px corners on layout and image elements, juxtaposed with perfectly circular radii on interactive buttons.",
  "contentWidth": "Fluid width utilizing the full viewport, with specific elements (like the structural line) inset from the center.",
  "spacingRhythm": "Highly generous, unstructured vertical rhythm driven by the scale of typography rather than a rigid grid, with massive blocks of whitespace separating sections."
}
```

### Reconstruction specification

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

- Root: 1440×39px; block; padding {"top":"0px","right":"0px","bottom":"0px","left":"0px"}; gap normal; background rgba(0, 0, 0, 0); radius 0px.
- Representative content widths: 518px.
- Layout containers: 0; cards/surfaces: 0; media elements: 0; browser animations: 0.

### 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: 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 “bleibtgleich'26 Navbar”.

Purpose: navbar section from the Home page of bleibtgleich'26.

Structure: 1440×39px root; block. Source layout label: 1440×39px root; block. 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 1440×39px root; block. Inspect the crop for image and content hierarchy.

Components: Navigation Bar, Hero, Carousel, Icon Button, Footer, Fixed Corner Branding, Interactive Media Mask, Structural Alignment Lines.

Style direction: minimal, typographic, bold, brutalist, monochromatic, structural.

Observed crop: 1440×39px (36.923:1). 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.
