# Sunday Features — Section Design Reference

Schema: Design Details SECTION.md v3.2
Source: https://www.sunday.ai/
Website: Sunday
Section ID: fb730ace-d951-4322-9248-0ad31c9cfdf8
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

1440×610px root; block

## Visual signature

minimal, typographic, photographic, corporate, tech-lifestyle, bento-grid treatment at 1440×610px. The crop spans 1582–2192px of a 15437px page.

## Components

- Navigation Bar
- Hero With Background Imagery
- Video Frame
- Feature Card
- FAQ Accordion
- Newsletter Form
- Outline Button
- Footer
- Floating Pill Header
- Asymmetric Media Grid

## 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: 1440×610px root; block
- Layout: 1440×610px root; block
- Styles: minimal, typographic, photographic, corporate, tech-lifestyle, bento-grid
- Components: Navigation Bar, Hero With Background Imagery, Video Frame, Feature Card, FAQ Accordion, Newsletter Form, Outline Button, Footer, Floating Pill Header, Asymmetric Media Grid
- Purpose: features section from the Home page of Sunday.
- Visual signature: rgb(255, 255, 255) with 1440×610px root; block. Inspect the crop for image and content hierarchy.

### Crop and composition

- Crop: 1440×610px; aspect ratio 2.361:1
- Page bounds: 1582–2192px of 15437px
- 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.

### Exact color evidence

The section samples record where each computed value was used. Functional roles come from the website-level classifier and remain separate.

```json
{
  "sectionUsage": [],
  "functionalPalette": [
    {
      "hex": "#000000",
      "name": "text",
      "role": "text",
      "source": "computed",
      "evidence": "color-2: computed rgb(0, 0, 0); AI role: #000000 provides high contrast for primary typography.",
      "sampleId": "color-2",
      "confidence": 1
    },
    {
      "hex": "#F7E731",
      "name": "accent",
      "role": "accent",

      "evidence": "color-5: computed rgb(243, 243, 240); AI role: #F3F3F0 acts as the dominant off-white background color for much of the page.",
      "sampleId": "color-5",
      "confidence": 0.9
    },
    {
      "hex": "#FFFFFF",
      "name": "surface",
      "role": "surface",
      "source": "computed",
      "evidence": "color-1: computed rgb(255, 255, 255); AI role: #FFFFFF used for distinct sections or cards over the off-white canvas.",
      "sampleId": "color-1",
      "confidence": 0.85
    }
  ]
}
```

### Design tokens

```json
{
  "radius": "Large border radii on media containers and feature cards; fully rounded (pill-shaped) radii on buttons, tags, and the navigation bar.",
  "density": "Low density. The layout prioritizes large typography and media over dense information packing.",
  "evidence": "Observed via the visual spacing in full-page screenshots, pill-shaped nav/buttons, and the widespread application of rounded corners on video frames.",
  "borderStyle": "Minimal use of borders, typically restricted to thin, semi-transparent 1px outlines on interactive elements or floating containers.",
  "buttonStyle": "Pill-shaped, often employing outline styles with dark borders and text, sometimes transitioning to dark solid fills.",
  "cornerStyle": "Consistent use of rounded corners across almost all structural elements, avoiding sharp edges.",
  "contentWidth": "Content is generally centered within a maximum width, though large media blocks stretch wider with inset padding.",
  "spacingRhythm": "Generous vertical spacing between distinct sections, creating clear breathing room. Internal padding in grid items is also substantial."
}
```

### Reconstruction specification

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

- Root: 1440×610px; block; padding {"top":"0px","right":"0px","bottom":"0px","left":"0px"}; gap normal; background rgb(255, 255, 255); radius 0px.
- Observed gaps: 24px.
- Representative content widths: 1392, 440, 408px.
- Layout containers: 2; cards/surfaces: 2; media elements: 3; 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 “Sunday Features”.

Purpose: features section from the Home page of Sunday.

Structure: 1440×610px root; block. Source layout label: 1440×610px root; block. Preserve the documented hierarchy and relationships; exact measurements were not deterministically captured.

Visual signature to preserve at the pattern level: rgb(255, 255, 255) with 1440×610px root; block. Inspect the crop for image and content hierarchy.

Components: Navigation Bar, Hero With Background Imagery, Video Frame, Feature Card, FAQ Accordion, Newsletter Form, Outline Button, Footer, Floating Pill Header, Asymmetric Media Grid.

Style direction: minimal, typographic, photographic, corporate, tech-lifestyle, bento-grid.

Observed crop: 1440×610px (2.361:1). 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.
