Aspid.MVVM

Conventions for writing XML documentation comments (`///`) in the Aspid.MVVM C# framework — `<summary>`, `<param>`, `<typeparam>`, `<returns>`, `<remarks>`, `<exception>`, `<inheritdoc/>`, hook methods, binder `<example>` includes, and class hierarchy-style summaries. Use this skill whenever writing, editing, or reviewing XML doc comments on classes, interfaces, methods, properties, events, binders, or attributes anywhere in the Aspid.MVVM repo, or when the user asks how to document something in this project, to add XML docs to a file, to write a summary for a binder, to format a `<param>` or `<returns>` block, or to fix inconsistent/missing documentation. Also triggers on phrases like "document this", "add XML docs", "write a summary for", "fix the docs on", "document the binder", or when editing `.cs` files that already contain `///` blocks.
