Checklist

• I have read AGENTS.md and CONTRIBUTING.md.
• dotnet build and dotnet test pass locally.
• I updated README.md / AGENTS.md if this changes what they describe.
• If this touches a device backend: I tested it against the real hardware (say which model/OS
  below). If you could not, say so explicitly rather than presenting it as tested.

Device/hardware tested against (if applicable)
