# One Platform for every AI Agent — Section Design Reference

Schema: Design Details SECTION.md v3.2
Source: https://www.sim.ai/
Website: Sim
Section ID: 83012649-34d8-4a3a-bea0-7b7c0690531f
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

1440×792px root; flex

## Visual signature

minimal, corporate, typographic, monochromatic-interface-mockups treatment at 1440×792px. The crop spans 2963–3755px of a 8419px page.

## Components

- Announcement Bar
- Navigation Bar
- Hero
- Primary Button
- Outline Button
- Product UI
- Logo Strip
- Video Frame
- Stat Block
- Feature Card
- Input Field
- Feature Collection
- Badge
- Footer
- Simulated Terminal Output
- Floating Action Input

## 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: 1440×792px root; flex
- Layout: 1440×792px root; flex
- Styles: minimal, corporate, typographic, monochromatic-interface-mockups
- Components: Announcement Bar, Navigation Bar, Hero, Primary Button, Outline Button, Product UI, Logo Strip, Video Frame, Stat Block, Feature Card, Input Field, Feature Collection, Badge, Footer, Simulated Terminal Output, Floating Action Input
- Purpose: features section from the Home page of Sim.
- Visual signature: rgba(0, 0, 0, 0) with 1440×792px root; flex. Inspect the crop for image and content hierarchy.

### Crop and composition

- Crop: 1440×792px; aspect ratio 1.818:1
- Page bounds: 2963–3755px of 8419px
- 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": "Buttons and input fields show significant rounding (pill-shaped or large radii), while larger structural cards have smaller, subtle rounding.",
  "density": "Low density; elements have ample breathing room, prioritizing readability and focus on single concepts at a time.",
  "evidence": "Observation of component layouts, padding around text blocks, border properties on cards (e.g., color-8), and button shapes across the entire page.",
  "borderStyle": "Thin, solid light gray borders define sections, cards, and UI mockups.",
  "buttonStyle": "Pill-shaped buttons; primary are dark solid fill with white text, secondary are transparent with thin gray borders.",
  "cornerStyle": "Mostly rounded corners on interactive elements (buttons, inputs) and container cards.",
  "contentWidth": "Centered content with a constrained maximum width, flanked by substantial margins on wider screens.",
  "spacingRhythm": "Generous vertical and horizontal padding, creating distinct logical sections separated by white space."
}
```

### Reconstruction specification

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

- Root: 1440×792px; flex; padding {"top":"0px","right":"40px","bottom":"0px","left":"40px"}; gap normal; background rgba(0, 0, 0, 0); radius 0px.
- Representative content widths: 818, 768, 256px.
- 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 “One Platform for every AI Agent”.

Purpose: features section from the Home page of Sim.

Structure: 1440×792px root; flex. Source layout label: 1440×792px 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 1440×792px root; flex. Inspect the crop for image and content hierarchy.

Components: Announcement Bar, Navigation Bar, Hero, Primary Button, Outline Button, Product UI, Logo Strip, Video Frame, Stat Block, Feature Card, Input Field, Feature Collection, Badge, Footer, Simulated Terminal Output, Floating Action Input.

Style direction: minimal, corporate, typographic, monochromatic-interface-mockups.

Observed crop: 1440×792px (1.818:1). 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.
