I built RenderAudit after finding invisible text on a live business site, what should it catch next?

A real client site had its main heading in white-on-white text for weeks.

Every SEO tool said the page was fine, because they read source code, not the rendered page. That bug became RenderAudit: it loads your site in a real browser, computes actual contrast on every element, and shows a health score in ~15 seconds (free, no signup, subs). Available on Claude/AI chats via MCP.

If you run it on your own site, I'd love to know: did it catch something you didn't know about? And what check would you want added next - I'm building in public and prioritizing by what people actually ask for.
