# Provably Correct Decision-Making Hero — Section Design Reference

Schema: Design Details SECTION.md v3.2
Source: https://www.atalanta.tech/
Website: Atalanta
Section ID: 0d86da17-8306-40ba-b3f4-0c74a587bf17
Status: deterministic evidence captured; editorial AI review pending

## Purpose

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

## Layout

1440×1237px root; grid; 1440px

## Visual signature

minimal, corporate, typographic, bold, cinematic, grid-based treatment at 1440×1242px. The crop spans 0–1242px of a 8935px page.

## Components

- Navigation Bar
- Hero With Background Imagery
- Feature Collection
- Contact Form
- Primary Button
- Footer
- Persistent Sidebar Indicator
- Oversized Footer Logo

## 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: hero
- Source type: hero
- Structure: grid
- Layout: 1440×1237px root; grid; 1440px
- Styles: minimal, corporate, typographic, bold, cinematic, grid-based
- Components: Navigation Bar, Hero With Background Imagery, Feature Collection, Contact Form, Primary Button, Footer, Persistent Sidebar Indicator, Oversized Footer Logo
- Purpose: hero section from the Home page of Atalanta.
- Visual signature: rgba(0, 0, 0, 0) with 1440×1237px root; grid; 1440px. Inspect the crop for image and content hierarchy.

### Crop and composition

- Crop: 1440×1242px; aspect ratio 1.159:1
- Page bounds: 0–1242px of 8935px
- 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.

### Design tokens

```json
{
  "radius": "0px on all visible components including input fields and buttons.",
  "density": "Low density, favoring large typography and significant negative space over cramped information.",
  "evidence": "Visual observation of sharp input boxes, visible grid lines separating the left sidebar from the main content, and DOM facts confirming thin borders and 0px border-radius patterns.",
  "borderStyle": "Subtle, thin solid 1px borders used to delineate the grid structure and input fields.",
  "buttonStyle": "Flat, unrounded rectangular containers with uppercase text.",
  "cornerStyle": "Sharp, 90-degree corners exclusively.",
  "contentWidth": "Full-bleed for background imagery, but text content is constrained within a multi-column grid system leaving a wide left margin.",
  "spacingRhythm": "Generous vertical spacing between distinct thematic sections, with tight, structured padding within the grid columns."
}
```

### Reconstruction specification

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

- Root: 1440×1237px; grid; padding {"top":"162px","right":"0px","bottom":"0px","left":"0px"}; gap normal; background rgba(0, 0, 0, 0); radius 0px.
- Observed gaps: 1, 5, 20px.
- Representative content widths: 989, 954, 808, 422, 355, 315px.
- Layout containers: 5; cards/surfaces: 0; media elements: 7; 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 hero section inspired by the design evidence titled “Provably Correct Decision-Making Hero”.

Purpose: hero section from the Home page of Atalanta.

Structure: grid. Source layout label: 1440×1237px root; grid; 1440px. 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 1440×1237px root; grid; 1440px. Inspect the crop for image and content hierarchy.

Components: Navigation Bar, Hero With Background Imagery, Feature Collection, Contact Form, Primary Button, Footer, Persistent Sidebar Indicator, Oversized Footer Logo.

Style direction: minimal, corporate, typographic, bold, cinematic, grid-based.

Observed crop: 1440×1242px (1.159:1). 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.
