# Designed to compose — Section Design Reference

Schema: Design Details SECTION.md v3.2
Source: https://parallel.ai/
Website: Parallel
Section ID: f83f390a-3b83-446f-aa8e-7a8216f428f2
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

1344×598px root; grid; 64px 64px 64px 64px 64px 64px 64px 64px 64px 64px 64px 64px

## Visual signature

minimal, typographic, corporate, bold, developer-centric, utilitarian treatment at 1440×598px. The crop spans 2805–3403px of a 13235px page.

## Components

- Navigation Bar
- Hero With Background Imagery
- Logo Strip
- Feature Card
- Comparison Table
- Testimonial Card
- FAQ Accordion
- Footer
- Primary Button
- Outline Button
- Badge
- Interactive Terminal UI
- Data Visualization Scatter Plot

## 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: grid
- Layout: 1344×598px root; grid; 64px 64px 64px 64px 64px 64px 64px 64px 64px 64px 64px 64px
- Styles: minimal, typographic, corporate, bold, developer-centric, utilitarian
- Components: Navigation Bar, Hero With Background Imagery, Logo Strip, Feature Card, Comparison Table, Testimonial Card, FAQ Accordion, Footer, Primary Button, Outline Button, Badge, Interactive Terminal UI, Data Visualization Scatter Plot
- Purpose: features section from the Home page of Parallel.
- Visual signature: rgba(0, 0, 0, 0) with 1344×598px root; grid; 64px 64px 64px 64px 64px 64px 64px 64px 64px 64px 64px 64px. Inspect the crop for image and content hierarchy.

### Crop and composition

- Crop: 1440×598px; aspect ratio 2.408:1
- Page bounds: 2805–3403px of 13235px
- 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": "Small border-radius (e.g., 2px-4px) on form elements and buttons, though largely imperceptible, presenting as sharp.",
  "density": "Low density; high amount of negative space around text blocks and between horizontal content bands.",
  "evidence": "Visual inspection of the screenshots shows wide margins, sharp-edged buttons ('Log in', 'API Playground'), solid color fills for primary buttons, and distinct 1px gray borders separating elements like the FAQ list.",
  "borderStyle": "Thin, 1px solid borders using light grays (color-32) for delineating sections, buttons, and UI mockups.",
  "buttonStyle": "Solid fill for primary actions with sharp corners; outlined with transparent backgrounds for secondary actions.",
  "cornerStyle": "Mostly square or very slightly rounded corners on elements like buttons and cards, leaning towards a sharp, technical look.",
  "contentWidth": "Constrained central column for text content (approx 800-1000px), with hero graphics and full-width background bands extending further.",
  "spacingRhythm": "Generous vertical spacing between major sections, creating a distinct, uncrowded layout. Grid layouts in features use moderate gaps."
}
```

### Reconstruction specification

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

- Root: 1344×598px; grid; padding {"top":"80px","right":"24px","bottom":"80px","left":"24px"}; gap 48px; background rgba(0, 0, 0, 0); radius 0px.
- Observed gaps: 6, 8, 48px.
- Representative content widths: 1344, 328, 323, 305px.
- Layout containers: 1; cards/surfaces: 0; media elements: 3; 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 “Designed to compose”.

Purpose: features section from the Home page of Parallel.

Structure: grid. Source layout label: 1344×598px root; grid; 64px 64px 64px 64px 64px 64px 64px 64px 64px 64px 64px 64px. 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 1344×598px root; grid; 64px 64px 64px 64px 64px 64px 64px 64px 64px 64px 64px 64px. Inspect the crop for image and content hierarchy.

Components: Navigation Bar, Hero With Background Imagery, Logo Strip, Feature Card, Comparison Table, Testimonial Card, FAQ Accordion, Footer, Primary Button, Outline Button, Badge, Interactive Terminal UI, Data Visualization Scatter Plot.

Style direction: minimal, typographic, corporate, bold, developer-centric, utilitarian.

Observed crop: 1440×598px (2.408:1). Treat this as evidence of composition, not a mandatory output size.
