# Natural selection is coming for your CRM — Section Design Reference

Schema: Design Details SECTION.md v3.2
Source: https://zero.inc/
Website: Zero
Section ID: ee3a77cf-957d-44b4-963e-7254b535dd38
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

1440×224px root; flex

## Visual signature

minimal, bold, soft, retro, product-centric-ui treatment at 1440×224px. The crop spans 12139–12363px of a 13530px page.

## Components

- Navigation Bar
- Hero
- Product UI
- Editorial Card
- Footer
- Pixel Art Scene Transition
- Floating UI Layer

## 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: 1440×224px root; flex
- Layout: 1440×224px root; flex
- Styles: minimal, bold, soft, retro, product-centric-ui
- Components: Navigation Bar, Hero, Product UI, Editorial Card, Footer, Pixel Art Scene Transition, Floating UI Layer
- Purpose: features section from the Home page of Zero.
- Visual signature: rgba(0, 0, 0, 0) with 1440×224px root; flex. Inspect the crop for image and content hierarchy.

### Crop and composition

- Crop: 1440×224px; aspect ratio 6.429:1
- Page bounds: 12139–12363px of 13530px
- 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.

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": "Primary buttons use full border-radius (pill shape). Product UI panels use approximately 12px-16px border-radius.",
  "density": "The overall marketing page has a relaxed density with large typographic blocks. Conversely, the embedded product mockups exhibit high information density, typical of a B2B SaaS tool.",
  "evidence": "Observations derived from button shapes in the nav, heading spacing, and the layout of the UI cards presented.",
  "borderStyle": "Mostly borderless design for marketing components, relying on shadows. Subtle, 1px solid borders (light gray) are used within the UI mockups to separate data rows and panes.",
  "buttonStyle": "Primary actions are solid dark reddish-brown (#2E0000) with white text, pill-shaped. Secondary actions are often pill-shaped outlines or ghost buttons with light hover states.",
  "cornerStyle": "Consistent rounded corners. Sharp corners are avoided. UI elements have moderate rounding, while buttons and chips are fully pill-shaped.",
  "contentWidth": "Main container appears wide but constrained, likely around 1200px max-width, allowing UI mockups to break out or stretch across the viewport slightly.",
  "spacingRhythm": "Generous vertical rhythm between major marketing sections (likely 120px+). Internal spacing within UI mockups is tight and structured to mimic complex software."
}
```

### Reconstruction specification

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

- Root: 1440×224px; flex; padding {"top":"0px","right":"40px","bottom":"44px","left":"40px"}; gap normal; background rgba(0, 0, 0, 0); radius 0px.
- Representative content widths: 634px.
- Layout containers: 1; 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 features section inspired by the design evidence titled “Natural selection is coming for your CRM”.

Purpose: features section from the Home page of Zero.

Structure: 1440×224px root; flex. Source layout label: 1440×224px root; flex. 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 1440×224px root; flex. Inspect the crop for image and content hierarchy.

Components: Navigation Bar, Hero, Product UI, Editorial Card, Footer, Pixel Art Scene Transition, Floating UI Layer.

Style direction: minimal, bold, soft, retro, product-centric-ui.

Observed crop: 1440×224px (6.429:1). 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.
