extends GutTest
## Behavioural checks on the chat box — the bottom-left all/team chat. They verify the typing
## gate (open / close drives `is_typing`, which the driver reads to suppress casts), the scope
## toggle, and that a sent line is echoed locally and announced while a blank send is dropped.
## Network delivery is a later slice and is not exercised here — the local echo and the gate are
## the whole of the first-pass logic.
