Title bar — single-line branded header at the top of the dashboard.
Renders a rich-text %Line{} via BB.TUI.Theme.brand_title/2, so
the bot icon, BB.TUI brand, robot module, and optional @ node
segment each carry their own color and modifier. The whole line
sits over Theme.title_bg/0 for visual separation from the panels
beneath it.
Pure function — takes state, returns a widget struct.
