## Purpose

This is a pricing 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

soft, editorial, hand-drawn, organic treatment at 1440×897px. The crop spans 9108–10005px of a 20824px page.

## Components

- Navigation Bar
- Hero With Background Imagery
- Testimonial Card
- Footer
- Outline Button
- Tilted Card Grid
- Hand Drawn Underline
- Product Card
- Feature Collection

## 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.

### 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": "93.6px",
      "family": "Exposure",
      "source": "computed",
      "traits": "Regular",
      "weight": "400",
      "evidence": "font-2: computed CSS at 1440×1000; AI role: Largest heading font, 93.6px serif ('Exposure'), used for major section titles.",
      "sampleId": "font-2",
      "confidence": 1,
      "lineHeight": "103px",
      "letterSpacing": "-1.9px"
    },
    {
      "role": "heading",
      "size": "72px",
      "family": "Exposure",
      "source": "computed",
      "traits": "Regular",
      "weight": "400",
      "evidence": "font-4: computed CSS at 1440×1000; AI role: 72px serif used in the hero and other prominent sections.",
      "sampleId": "font-4",
      "confidence": 0.95,
      "lineHeight": "64.8px",
      "letterSpacing": "normal"
    },
    {
      "role": "body",
      "size": "18px",
      "family": "Exposure",
      "source": "computed",
      "traits": "Regular",
      "weight": "400",
      "evidence": "font-9: computed CSS at 1440×1000; AI role: 18px standard body copy used for list items and general links.",
      "sampleId": "font-9",
      "confidence": 0.9,
      "lineHeight": "21.6px",
      "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": "#292929",
      "name": "text",
      "role": "text",
      "source": "computed",
      "evidence": "color-2: computed rgb(41, 41, 41); AI role: Dark gray (#292929) used heavily for main typography.",
      "sampleId": "color-2",
      "confidence": 0.95
    },
    {
      "hex": "#FFFFFF",
      "name": "canvas",
      "role": "canvas",
      "source": "computed",
      "evidence": "color-1: computed rgb(255, 255, 255); AI role: White background used for many sections.",
      "sampleId": "color-1",
      "confidence": 0.9
    },
    {
      "hex": "#121214",
      "name": "surface",
      "role": "surface",
      "source": "computed",
      "evidence": "color-3: computed rgb(18, 18, 20); AI role: Dark gray/black (#121214) used for the footer background.",
      "sampleId": "color-3",
      "confidence": 0.9
    },
    {
      "hex": "#E8CEFF",
      "name": "primary action",
      "role": "primary-action",
      "source": "computed",
      "evidence": "color-5: computed rgb(232, 206, 255); AI role: Lavender (#E8CEFF) used for buttons, interactive elements, and hover states.",
      "sampleId": "color-5",
      "confidence": 0.9
    }
  ]
}
```

### Design tokens

```json
{
  "radius": "Small to medium border radii (e.g., on feature cards and small pill-shaped tags).",
  "density": "Low density; the design heavily favors open space, large text, and isolated imagery over packed information.",
  "evidence": "Observed via the structural layout of DOM elements, CSS padding/margins implied by whitespace, and visual styling of buttons/cards.",
  "borderStyle": "Mostly borderless designs relying on color contrast and drop shadows, except for thin subtle dividers or borders on specific buttons.",
  "buttonStyle": "Pill-shaped or rounded rectangle buttons, often in the primary lavender color or as bordered options, frequently featuring an arrow icon.",
  "cornerStyle": "Slightly rounded corners on buttons, cards, and image containers, contributing to the soft visual style.",
  "contentWidth": "Wide, often edge-to-edge for background colors and large imagery, with text content constrained to readable central columns or structured split grids.",
  "spacingRhythm": "Generous vertical spacing between major sections, utilizing extensive whitespace to separate content blocks and allow the large typography to breathe."
}
```

### 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": 9108,
      "bottom": 10005,
      "pageHeight": 20824
    }
  },
  "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": "2026-10-10T05:32:41.096Z",
  "viewportWidth": 1440,
  "bounds": {
    "top": 9108,
    "bottom": 10005,
    "pageHeight": 20824
  },
  "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 pricing section inspired by the design evidence titled “Student housing floor-plan listings”.

Purpose: pricing section from the Home page of 21Oaks Student Apartments • USC & Williams-Brice.

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, Testimonial Card, Footer, Outline Button, Tilted Card Grid, Hand Drawn Underline, Product Card, Feature Collection.

Style direction: soft, editorial, hand-drawn, organic.

Observed crop: 1440×897px (1.605:1). 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.
