**What we look for.** Whether your pages show their content with JavaScript turned off.

**Why it matters.** Most AI crawlers don't run JavaScript. A page that renders only in the browser looks empty to them.

**How to pass.** Render content on the server, or prerender your public pages.

Run it: `npx backwatch your-site.com --pillar readability` and find `content-no-js` in the report.
