-    Chat Pane Component - reusable chat scaffold.
-    Usage: {{template "chat-pane" dict "ID" "main"}}
-    Creates mount points: {ID}ChatMessages, {ID}ChatInput, {ID}SendBtn, {ID}ModelSel
-    ChatPane.create() in chat-pane.js binds to these IDs.
-
-    The header bar ({ID}ChatHeader) is hidden by default.
-    Standalone panes (editor assist) show it for chat switching + model selection.
