About this sample

This site exists for one reason: to prove that a brand-new Next.js marketing build can pass every shipped build-websites-tools gate by following only the published README. No private templates, no internal Site Clinic scaffolding, no copied scripts.

What was used

• Next.js 16 App Router, written by hand.
• build-websites-tools pinned to v0.3.1, installed as a GitHub tag dependency exactly as the README describes.
• One gate.config.json derived from the marketing-site template.
• A static public/robots.txt with the matrix-required AI policy comment block.
• A static public/llms.txt with a Markdown heading.
• JSON-LD for Organization and WebSite served from the root layout.

What it shows

The four gates run at prebuild. Each one fails loudly when its invariant breaks. Each one passes on this build. The same package is in use on every site on Site Clinic.
