# Alternating media blocks on dark ground — Section Design Reference

Schema: Design Details SECTION.md v3.2
Source: https://bedrockrobotics.com/
Website: Bedrock Robotics
Section ID: c9a07d28-0634-4c5b-bc2a-b095c86474b5
Design Details page: https://designdetails.io/sections/bedrockrobotics-com--home--features-4
Status: deterministic evidence captured; editorial AI review pending

## Purpose

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

## Layout

1440×3000px root; block

## Visual signature

bold, photographic, minimal, corporate, typographic, industrial, cinematic treatment at 960×600px. The crop spans 4970–7970px of a 11796px page.

## Components

- Hero With Background Imagery
- Navigation Bar
- Primary Button
- Newsletter Form
- Footer
- Video Frame
- Split Media/text Block
- Giant Typographic Watermark

## 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: features
- Source type: features
- Structure: 1440×3000px root; block
- Layout: 1440×3000px root; block
- Styles: bold, photographic, minimal, corporate, typographic, industrial, cinematic
- Components: Hero With Background Imagery, Navigation Bar, Primary Button, Newsletter Form, Footer, Video Frame, Split Media/text Block, Giant Typographic Watermark
- Purpose: features section from the Home page of Bedrock Robotics.
- Visual signature: rgb(85, 80, 71) with 1440×3000px root; block. Inspect the crop for image and content hierarchy.
- Place on the page: 6 of 10, after Other (`1f7c4069-0da5-47b8-b8c1-e43dbbed64da`), before Testimonials (`abbdfb35-0519-445c-8720-7458762e03a2`)

### Crop and composition

- Crop: 960×600px; aspect ratio 1.6:1
- Page bounds: 4970–7970px of 11796px
- 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.

### Design tokens

```json
{
  "radius": "0px radius is standard across interactive elements and layout blocks.",
  "density": "Very low density, prioritizing large-scale imagery and massive text over high information volume, creating a breathing, cinematic feel.",
  "evidence": "Observed from the full-width video headers, sharp-edged yellow buttons, unbordered input fields, and the stark color block transitions between sections.",
  "borderStyle": "Borders are largely absent; visual separation is achieved through stark background color changes (light beige to dark olive) or media edges.",
  "buttonStyle": "Flat, unshadowed rectangular blocks with solid fill colors (yellow) and contrasting dark text, utilizing a simple right-pointing arrow icon.",
  "cornerStyle": "Strictly sharp, 90-degree corners on all primary structural containers, buttons, and input fields.",
  "contentWidth": "Media and major typographic elements often bleed to the edges, while body text is contained within comfortable, though wide, reading columns, often offset to one side.",
  "spacingRhythm": "Extremely generous vertical padding, often utilizing full viewport heights for distinct sections, with large gaps between media elements and text."
}
```

### Reconstruction specification

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

- Root: 1440×3000px; block; padding {"top":"0px","right":"0px","bottom":"0px","left":"0px"}; gap normal; background rgb(85, 80, 71); radius 0px.
- Observed gaps: 2px.
- Representative content widths: 520px.
- Layout containers: 1; 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 features section inspired by the design evidence titled “Alternating media blocks on dark ground”.

Purpose: features section from the Home page of Bedrock Robotics.

Structure: 1440×3000px root; block. Source layout label: 1440×3000px root; block. Preserve the documented hierarchy and relationships; exact measurements were not deterministically captured.

Visual signature to preserve at the pattern level: rgb(85, 80, 71) with 1440×3000px root; block. Inspect the crop for image and content hierarchy.

Components: Hero With Background Imagery, Navigation Bar, Primary Button, Newsletter Form, Footer, Video Frame, Split Media/text Block, Giant Typographic Watermark.

Style direction: bold, photographic, minimal, corporate, typographic, industrial, cinematic.

Observed crop: 960×600px (1.6:1). 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.
