## Overview
An oversized emerald-to-lime display headline sits above a short subtitle and paired developer onboarding actions. Inspected at 1440px desktop and 390px mobile widths on September 30, 2026.

## Colors
Palette tokens describe the observed visual roles. Pair emerald accents and pale mint glows with rounded white surfaces. Large tight display type anchors the page; code panels introduce black contrast. Transparent and gradient text layers must be considered with their painted background, not interpreted as solid-color text.

## Typography
The sampled heading uses "Inter Tight", "Inter Tight Fallback" at 128px, weight 700, with 128px leading. Supporting sample: Inter, "Inter Fallback", 24px / 32px. These are computed styles at capture width, not fixed requirements for every breakpoint. Use licensed font assets or deliberate substitutes.

## Layout
Center the tight headline and short copy; keep the primary green button next to a quieter agent-setup control. At mobile width reduce scale and stack controls. 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
The headline paint is a gradient; a transparent computed text color does not mean invisible typography.

## 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.
