## Overview
A template-discovery section uses a left option list and a pale-yellow detail panel with an action, description and technology chips. Inspected at 1440px desktop and 390px mobile widths on September 30, 2026.

## Colors
Palette tokens describe the observed visual roles. Use a precise white grid, black pill actions, orange-red highlights and expressive dithered landscape artwork. Pale blue product demos contrast with dense black interface text. Transparent and gradient text layers must be considered with their painted background, not interpreted as solid-color text.

## Typography
The sampled heading uses gtPlanar, "gtPlanar Fallback", system-ui, Arial, sans-serif at 36px, weight 500, with 37.8px leading. Supporting sample: plain, "plain Fallback", system-ui, Arial, sans-serif, 16px / 24px. These are computed styles at capture width, not fixed requirements for every breakpoint. Use licensed font assets or deliberate substitutes.

## Layout
Use a clear desktop master-detail layout; on mobile replace the desktop option list with the observed dropdown above the selected detail panel. Keep badges subordinate to the selected template description. Exact responsive breakpoints were not measured.

## Elevation & Depth
Preserve separation through the reference’s surface contrast, border rules and whitespace. Avoid adding heavy shadows to a flat interface. Shadow strength is visual guidance, not a measured token.

## Shapes
Keep the visible distinction between content panels, fields and actions. Match the photographed corner treatment rather than applying one global radius; measured element radii are retained in the evidence.

## Components
Only the default selected template is captured; alternative options were not exercised.

## Do's and Don'ts
Do adapt hierarchy, spacing and responsive ordering with your own brand and truthful copy. Do not reuse customer endorsements or performance numbers as your own. Do not infer hover, keyboard, validation, dark-mode or accessibility compliance from static images.
