Accept Header Test Matrix

Four variants for comparing how AI systems handle raw HTML, server-visible schema, inline JavaScript injection, and external JavaScript injection.

/test/raw

Raw HTML Control

Control page with no structured data.

/test/server-schema

Server-Side JSON-LD

JSON-LD is present in the initial HTML response.

/test/js-inline

Inline JS Injection

Inline JavaScript builds JSON-LD inside the browser.

/test/js-external

External JS Injection

A bootstrap snippet loads an external loader, which fetches a separate schema payload.
