||
Landing state covers two cases: (a) a brand-new chat that
|
||
hasn't sent anything yet, and (b) the user clicking 「新对话」
|
||
mid-stream. In (b) the underlying useStream's internal
|
||
stream.values takes one or two effect ticks to clear, so
|
||
rendering MessageList unconditionally would leak the previous
|
||
conversation under the welcome card. Skip rendering during
|
||
the landing state to guarantee a clean slate.
