- Use raw string literals (or interpolated raw string literals) for paragraph-style output.
- Use target-typed `new` when the target type is evident.
- Use `new` to construct objects. Omit the type name when the target type is evident.
- Use collection expressions to initialize collections and arrays wherever possible.

- Convert eligible value-producing `switch` statements to switch expressions.

- Remove `this.` where it's unnecessary.
- Add `using` statements for disposable types, and remove redundant calls to `Close()` or `Dispose()`.
- Prune unnecessary package references from project files.
- Use compound assignment.
- Replace calls to obsolete APIs with their recommended replacements (per the `ObsoleteAttribute` message and official docs). For example, replace `WebRequest` with `HttpClient`.

Don't introduce `var`; this repository prefers explicit types.
