VT server example

Use the VT server example to understand status advertisement, upload handling, and the protocol/state boundary.

Look for:

  • examples/vt_server_demo.rs
  • the VtServer plugin on the session facade (see The session facade)

Remember: VTServer is the protocol/state machine. Hosted Rust code can replay its accepted render effects through VtRenderRuntime and the framebuffer/GTUI backends, but the server itself is not a GUI window or product UI.
