# Signal & Action Primitives — Section Design Reference

Schema: Design Details SECTION.md v3.2
Source: https://www.mecka.ai/
Website: Mecka
Section ID: 406fee66-a0bd-4456-9750-c623ac3bfddf
Status: deterministic evidence captured; editorial AI review pending

## Purpose

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

## Layout

1440×1259px root; block

## Visual signature

illustrative, minimal, typographic, retro, schematic-blueprint, technical-interface treatment at 1440×1134px. The crop spans 8799–9933px of a 13234px page.

## Components

- Navigation Bar
- Hero
- Logo Strip
- Feature Card
- FAQ Accordion
- Primary Button
- Footer
- Exploded View Illustration
- Technical Legend Table
- Signal Primitives 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: feature grid
- Source type: feature-grid
- Structure: 1440×1259px root; block
- Layout: 1440×1259px root; block
- Styles: illustrative, minimal, typographic, retro, schematic-blueprint, technical-interface
- Components: Navigation Bar, Hero, Logo Strip, Feature Card, FAQ Accordion, Primary Button, Footer, Exploded View Illustration, Technical Legend Table, Signal Primitives Grid
- Purpose: feature-grid section from the Home page of Mecka.
- Visual signature: rgb(12, 10, 7) with 1440×1259px root; block. Inspect the crop for image and content hierarchy.

### Crop and composition

- Crop: 1440×1134px; aspect ratio 1.27:1
- Page bounds: 8799–9933px of 13234px
- 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 the main floating header use maximum border-radius (pill shape), while cards and grid cells have 0px border-radius.",
  "density": "Density varies intentionally; technical diagrams and 'Bill of Materials' are highly dense with small mono text, while major typographic headings have expansive whitespace.",
  "evidence": "Visible grid lines in the background. The floating nav pill at the top. The rigid, tabular layout of the 'Bill of Materials' and 'The Challenge' features.",
  "borderStyle": "Extensive use of solid, 1px (hairline) borders to construct the 'blueprint' grid, separate table rows, and divide columns.",
  "buttonStyle": "Primary actions use solid, bold-colored pill shapes. Other interactable elements use subtle hover states with thin borders or small icon arrows.",
  "cornerStyle": "Mix of very sharp corners for content blocks and structural borders, contrasting with fully rounded 'pill' shapes for interactive floating elements like the nav bar.",
  "contentWidth": "Content generally spans a wide max-width, adhering to the underlying grid structure with generous horizontal padding.",
  "spacingRhythm": "Sections are divided by distinct horizontal lines or full background color changes. The layout relies heavily on a structured, visible grid that defines padding and alignment."
}
```

### Reconstruction specification

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

- Root: 1440×1259px; block; padding {"top":"144px","right":"0px","bottom":"144px","left":"0px"}; gap normal; background rgb(12, 10, 7); radius 0px.
- Representative content widths: 628, 533, 272px.
- Layout containers: 0; cards/surfaces: 0; media elements: 10; browser animations: 20.

### 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 feature grid section inspired by the design evidence titled “Signal & Action Primitives”.

Purpose: feature-grid section from the Home page of Mecka.

Structure: 1440×1259px root; block. Source layout label: 1440×1259px root; block. Preserve the documented hierarchy and relationships; exact measurements were not deterministically captured.

Visual signature to preserve at the pattern level: rgb(12, 10, 7) with 1440×1259px root; block. Inspect the crop for image and content hierarchy.

Components: Navigation Bar, Hero, Logo Strip, Feature Card, FAQ Accordion, Primary Button, Footer, Exploded View Illustration, Technical Legend Table, Signal Primitives Grid.

Style direction: illustrative, minimal, typographic, retro, schematic-blueprint, technical-interface.

Observed crop: 1440×1134px (1.27:1). 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.
