Section ID: 9bef61ed-1575-429d-8a24-301b6c8fb06b
Design Details page: https://designdetails.io/sections/duna-digital--home--other-9bef61ed
Status: deterministic evidence captured; editorial AI review pending

## Purpose

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

## Layout

captured layout

## Visual signature

typographic, minimal, bold, corporate, eco-tech treatment at 1440×543px. The crop spans 1716–2259px of a 10776px page.

## Components

- Navigation Bar
- Hero With Background Imagery
- Primary Button
- Feature Collection
- Stat Block
- Logo Strip
- FAQ Accordion
- Contact Form
- Footer
- Mixed Typography Heading
- Code Snippet Block

## 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

- 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.

```json
{
  "sectionScale": [],
  "siteRoles": [
    {
      "role": "display",
      "size": "60px",
      "family": "Glazier",
      "source": "computed",
      "traits": "Regular",
      "weight": "400",
      "evidence": "font-29: computed CSS at 1440×1000; AI role: Glazier serif font at 60px, used as an accent within major headings.",
      "sampleId": "font-29",
      "confidence": 0.95,
      "lineHeight": "61.2px",
      "letterSpacing": "normal"
    },
    {
      "role": "heading",
      "size": "60px",
      "family": "PP Mori",
      "source": "computed",
      "traits": "Regular",
      "weight": "600",
      "evidence": "font-4: computed CSS at 1440×1000; AI role: PP Mori at 60px, used for primary section headings.",
      "sampleId": "font-4",
      "confidence": 0.95,
      "lineHeight": "61.2px",
      "letterSpacing": "-1.2px"
    },
    {
      "role": "body",
      "size": "17px",
      "family": "PP Mori",
      "source": "computed",
      "traits": "Regular",
      "weight": "400",
      "evidence": "font-10: computed CSS at 1440×1000; AI role: PP Mori at 17px, used for standard paragraph text and descriptions.",
      "sampleId": "font-10",
      "confidence": 0.9,
      "lineHeight": "28.1px",
      "letterSpacing": "normal"
    },
    {
      "role": "mono",
      "size": "20px",
      "family": null,
      "source": "computed",
      "traits": "Regular",

      "confidence": 0.95,
      "lineHeight": "36px",
      "letterSpacing": "normal"
    }
  ]
}
```

### 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": "#F3F5EE",
      "name": "canvas",
      "role": "canvas",
      "source": "computed",
      "evidence": "color-2: computed rgb(243, 245, 238); AI role: Off-white #F3F5EE used as the primary background for most sections.",
      "sampleId": "color-2",
      "confidence": 0.95
    },
    {
      "hex": "#232B16",
      "name": "text",
      "role": "text",
      "source": "computed",
      "evidence": "color-1: computed rgb(35, 43, 22); AI role: Deep olive #232B16 used as the primary text color and surface color for dark sections.",
      "sampleId": "color-1",
      "confidence": 0.95
    },
    {
      "hex": "#D4FF86",
      "name": "primary action",
      "role": "primary-action",
      "source": "computed",
      "evidence": "color-3: computed rgb(212, 255, 134); AI role: Bright lime green #D4FF86 used for accents, buttons, and code highlights.",
      "sampleId": "color-3",
      "confidence": 0.95
    },
    {
      "hex": "#666C5B",
      "name": "muted text",
      "role": "muted-text",
      "source": "computed",
      "evidence": "color-5: computed rgb(102, 108, 91); AI role: Muted olive #666C5B used for secondary information.",
      "sampleId": "color-5",
      "confidence": 0.85
    }
  ]
}
```

### Design tokens

```json
{
  "radius": "Buttons and specific badges employ high border-radius values resulting in pill shapes.",
  "density": "Low visual density; relies on extensive whitespace and large typography to pace reading.",
  "evidence": "Based on the consistent padding observed between sections, the pill buttons in the header and forms, and the fine line dividers in the 'Selected work' and FAQ sections.",
  "borderStyle": "Thin, semi-transparent hairline borders (#232B16 at low opacity) heavily used as horizontal dividers for lists and tables.",
  "buttonStyle": "Primary buttons feature a dark solid background with text and an inset circular icon in the bright accent color.",
  "cornerStyle": "Fully rounded (pill-shaped) interactive elements contrasting with sharp, rectilinear container boundaries.",
  "contentWidth": "Content is constrained to a wide but centralized maximum width with consistent generous outer margins.",
  "spacingRhythm": "Generous macro-spacing separating distinct functional sections; micro-spacing utilizes strict grid alignment with clear dividers."
}
```

### Reconstruction specification

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

- Root container was not deterministically isolated.
- Layout containers: 0; cards/surfaces: 0; media elements: 0; browser animations: 0.

#### Container, grid, and spacing

```json
{
  "viewport": {
    "width": 1440,
    "captureBounds": {
      "top": 1716,
      "bottom": 2259,
      "pageHeight": 10776
    }
  },
  "container": null,
  "spacing": {
    "observedGapsPx": [],
    "representativeContentWidthsPx": []
  },
  "columns": []
}
```

#### Cards and surfaces

```json
{
  "cards": [],
  "surfaces": {
    "radii": [],
    "borders": [],
    "shadows": []
  }
}
```

#### Media treatment

```json
[]
```

#### Browser-exposed animation parameters

```json
[]
```

### 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.

```json
{
  "schema": "little-details-section-measurements-v1",
  "source": "saved DOM/CSS element and animation maps",
  "capturedAt": "2026-10-10T05:22:51.043Z",
  "viewportWidth": 1440,
  "bounds": {
    "top": 1716,
    "bottom": 2259,
    "pageHeight": 10776
  },
  "root": null,
  "spacing": {
    "gapsPx": [],
    "representativeContentWidthsPx": []
  },
  "columns": [],
  "cards": [],
  "surfaces": {
    "radii": [],
    "borders": [],
    "shadows": []
  },
  "media": [],
  "animations": [],
  "coverage": {
    "elementsInSection": 0,
    "cards": 0,
    "media": 0,
    "animations": 0
  },
  "limitations": [
    "Values describe the captured desktop viewport and may change at other breakpoints.",
    "Transforms, sticky layers, and virtualized content can make the inferred section root approximate.",
    "Animations include browser-exposed Web Animations API state; CSS or script motion that was inactive at capture time may be absent."
  ]
}
```

### 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: 6/7
- Can build: Yes
- Missing facts: section-specific computed typography and color samples; timestamped authored motion
- Warning: Buildable with adaptations for these unsupported facts: section-specific computed typography and color samples; timestamped authored motion.

### Agent implementation prompt

Create an original other section inspired by the design evidence titled “Code scroll animation transition”.

Purpose: other section from the Home page of DUNA Digital.

Structure: captured layout. Source layout label: captured layout. Preserve the documented hierarchy and relationships; exact measurements were not deterministically captured.

Visual signature to preserve at the pattern level: Captured visual surface with captured layout. Inspect the crop for image and content hierarchy.

Components: Navigation Bar, Hero With Background Imagery, Primary Button, Feature Collection, Stat Block, Logo Strip, FAQ Accordion, Contact Form, Footer, Mixed Typography Heading, Code Snippet Block.

Style direction: typographic, minimal, bold, corporate, eco-tech.

Observed crop: 1440×543px (2.652:1). Treat this as evidence of composition, not a mandatory output size.

No section-bounded typography samples were measured.

No section-bounded color samples were measured.

Exact section measurements from the saved element map: spacing {"gapsPx":[],"representativeContentWidthsPx":[]}; surfaces {"radii":[],"borders":[],"shadows":[]}

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.
