This page tests itself.
Everything above this line is a claim. This is not. The suite below is real, it runs in your browser against this document, and it has no idea this section exists.
Six real defects, injected into this live page. Watch the suite go red, then fix them one at a time and watch it come back.

Three that show the range.
Each one opens as its own page — the problem, what I actually did, and what changed.
