/**

|
* Tests for the learner-facing instructor intro selector (avatar hover title).
|
|
*
|
|
* Locks the "show curated description, fall back to nothing when blank/missing"
|
|
* rule. The avatar then renders `agentIntro ?? agentName` as a native `title`,
|
|
* so old projects (which may already carry a description) and new projects both
|
|
* surface the intro, and the cursor never changes.
