Schema: Design Details SECTION.md v3.2
Source: https://www.keytail.ai/
Website: Keytail
Section ID: f3064cf6-929c-4471-824c-706711807739
Design Details page: https://designdetails.io/sections/keytail-ai--home--navbar-f3064cf6
Status: deterministic evidence partially captured; editorial AI review pending

## Purpose

This is a navbar 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

minimal, corporate, typographic, photographic, saas treatment at 1440×58px. The crop spans 0–58px of a 8479px page.

## Components

- Navigation Bar
- Hero
- Product UI
- Feature Card
- Primary Button
- Ghost Button
- FAQ Accordion
- Footer
- Stat Block
- Product Mockup Feature Showcase
- Input Style CTA

## 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: navigation
- Source type: navbar
- Structure: captured layout
- Layout: captured layout
- Styles: minimal, corporate, typographic, photographic, saas
- Components: Navigation Bar, Hero, Product UI, Feature Card, Primary Button, Ghost Button, FAQ Accordion, Footer, Stat Block, Product Mockup Feature Showcase, Input Style CTA
- Purpose: navbar section from the Home page of Keytail.
- Visual signature: Captured visual surface with captured layout. Inspect the crop for image and content hierarchy.

- 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": "120px",
      "family": "abcDiatype",
      "source": "computed",
      "traits": "Regular",
      "weight": "400",
      "evidence": "font-3: computed CSS at 1440×1000; AI role: 120px 'abcDiatype' used for the massive main hero headline 'Get found. Automatically.'",
      "sampleId": "font-3",
      "confidence": 0.95,
      "lineHeight": "108px",
      "letterSpacing": "-6px"
    },
    {
      "role": "heading",
      "size": "72px",
      "family": "abcDiatype",

      "lineHeight": "75.6px",
      "letterSpacing": "-3.6px"
    },
    {
      "role": "body",
      "size": "16px",

      "source": "computed",
      "traits": "Regular",
      "weight": "400",
      "evidence": "font-7: computed CSS at 1440×1000; AI role: 16px 'abcDiatype' used for standard descriptive paragraph text across feature descriptions.",

      "confidence": 0.9,
      "lineHeight": "20px",
      "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": "#111111",
      "name": "text",
      "role": "text",
      "source": "computed",
      "evidence": "color-5: computed rgb(17, 17, 17); AI role: Near black (#111111) used for primary headings and important text for high legibility.",
      "sampleId": "color-5",
      "confidence": 0.95
    },
    {
      "hex": "#FFFFFF",
      "name": "canvas",
      "role": "canvas",
      "source": "computed",
      "evidence": "color-1: computed rgb(255, 255, 255); AI role: Pure white (#FFFFFF) used as the primary background for major content sections.",
      "sampleId": "color-1",
      "confidence": 0.9
    },
    {
      "hex": "#000000",
      "name": "primary action",
      "role": "primary-action",
      "source": "computed",
      "evidence": "color-2: computed rgb(0, 0, 0); AI role: Black (#000000) used for the primary 'Get started' button and other key actionable elements.",
      "sampleId": "color-2",
      "confidence": 0.9
    },
    {
      "hex": "#666666",
      "name": "muted text",
      "role": "muted-text",
      "source": "computed",
      "evidence": "color-10: computed rgb(102, 102, 102); AI role: Medium gray (#666666) used for secondary body text and descriptions to establish hierarchy.",
      "sampleId": "color-10",
      "confidence": 0.85
    },
    {
      "hex": "#F4F5F0",
      "name": "surface",
      "role": "surface",
      "source": "computed",
      "evidence": "color-3: computed rgb(244, 245, 240); AI role: Off-white/light gray (#F4F5F0) used as a background color for specific sections to create contrast with the main canvas.",
      "sampleId": "color-3",
      "confidence": 0.8
    },
    {
      "hex": "#E5E5E5",
      "name": "border",
      "role": "border",
      "source": "computed",
      "evidence": "color-20: computed rgb(229, 229, 229); AI role: Light gray (#E5E5E5) used for subtle borders around elements like the chart container and buttons.",
      "sampleId": "color-20",
      "confidence": 0.8
    }
  ]
}
```

### Design tokens

```json
{
  "radius": "Mixed. Pill-shaped buttons use fully rounded radii. Feature cards and product mockups use moderate rounding (likely 12px-24px range).",
  "density": "Low density. The design prioritizes whitespace and large typography over packing in information.",
  "evidence": "Observed from the overall page layout, specifically the spacing around headings, the shape of the 'Get started' and 'Try demo' buttons, and the thin borders on the chart container.",
  "borderStyle": "Subtle and minimal. Borders are generally thin (1px) and use light grays to define edges without adding visual weight.",
  "buttonStyle": "Solid fill (black or white) for primary/secondary actions, often pill-shaped. Ghost/toggle variants use transparent or very light backgrounds with text changes.",
  "cornerStyle": "Predominantly rounded corners. Buttons and cards use significant border radii (pill shapes for smaller buttons, softer rounded rectangles for larger containers).",
  "contentWidth": "Content is generally centered and constrained to a readable max-width, though background imagery and some full-width sections break this constraint.",
  "spacingRhythm": "Generous vertical rhythm with significant padding between major sections. Elements within sections have tighter, logical grouping."
}
```

### 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": null,
    "captureBounds": null
  },
  "container": null,
  "spacing": {
    "observedGapsPx": [],
    "representativeContentWidthsPx": []
  },
  "columns": []
}
```

#### Cards and surfaces

```json
{
  "cards": [],
  "surfaces": null
}
```

#### 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
null
```

### 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: unknownpx 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: 5/7
- Can build: Yes
- Missing facts: section-specific computed typography and color samples; section-level geometry, surfaces, media treatment, and animation parameters; timestamped authored motion
- Warning: Buildable with adaptations for these unsupported facts: section-specific computed typography and color samples; section-level geometry, surfaces, media treatment, and animation parameters; timestamped authored motion.

### Agent implementation prompt

Create an original navigation section inspired by the design evidence titled “Keytail Navbar”.

Purpose: navbar section from the Home page of Keytail.

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, Product UI, Feature Card, Primary Button, Ghost Button, FAQ Accordion, Footer, Stat Block, Product Mockup Feature Showcase, Input Style CTA.

Style direction: minimal, corporate, typographic, photographic, saas.

Observed crop: 1440×58px (24.828:1). 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.

No saved element-map measurements were available; do not invent exact source spacing, card, media, or animation values.

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.
