👋 Hi @hainenber, thanks for the pull request! A scan flagged a concern with it. Could you please take a look?

[text-image-alt-text] The following image seems to have default alt text, rather than something informative:

<img width="913" height="160" alt="image" src="https://github.com/user-attachments/assets/533b35e7-3b71-46d3-bc6c-250404d33b32" />

Alternative text, or "alt text", is a description attached to an image. It allows non-sighted users and tools to understand the image despite not being able to visually see it. To resolve this report, add descriptive alt text to the image.

Thank you! We'll probably merge this early next week unless @JoshuaKGoldberg has concerns. It does work when I repro locally, exact same result :)
