### Claim evidence

I am requesting ownership of the namespace `shadelightdev`.

My GitHub account is `Shadelight`, and I am the owner and maintainer of the IA Usage project:

https://github.com/Shadelight/ia-usage-bar

The extension published under this namespace is:

shadelightdev.ia-usage

The namespace `shadelightdev` was chosen because the namespace `Shadelight` was rejected by Open VSX for being too similar to the existing namespace `Hazelight`.

I am also the publisher/maintainer of IA Usage on the Visual Studio Marketplace under the Shadelight identity.

The repository, extension source code, release workflow, package metadata, and publishing history are all controlled by this GitHub account.

Please grant ownership of the `shadelightdev` namespace to my Open VSX account.

Relevant repository:
https://github.com/Shadelight/ia-usage-bar

Extension ID:
shadelightdev.ia-usage

GitHub owner:
Shadelight

Start by reviewing the namespace claim checklist and searching for shadelightdev on open-vsx.org, then verify the Shadelight publisher and ia-usage extension on the Visual Studio Marketplace. Check the linked ia-usage-bar repository and package metadata for the claimed ownership evidence; done means the evidence is verified and the namespace is granted or the request receives a documented decision.
