We haven't quite formalised this yet, but we need to start tracking asset licenses more properly. Even if we don't end up using that precise tooling contrary to my expectation, I think reuse works well as a stopgap solution as proposed in #2706. Can you add this for the image in this PR?

Sure! @officialdakari, would you be able to offer some insight here in regard to the license used for logo.svg?

@HarHarLinks: Which method is preferred for adding REUSE information: within the file itself or in a separate *.license file?

I can see that a separate .license file is used for /bridges/activitypub/logo.svg, so I’ll just mirror that choice for consistency's sake.

For the record, while the license for extera-next.svg is not currently noted publicly, after asking in #extera:extera.xyz, I have confirmed with the client's maintainer how the logo is licensed and who created it. I've added extera-next.svg.license, which contains this information. See fd4c00.
