 * The model-endpoint segment folds in the linked project name when connected
 * (`AI Gateway (project)`), drops to a bare `AI Gateway` when connected without
 * a linked project, and goes yellow with a `⚠` when the gateway has no usable
 * credential. Everything else renders dim except the yellow action signals (a
 * pending deploy, the not-connected gateway). On narrow widths segments degrade
 * in order, the endpoint first and then the model, keeping tokens and the
 * pending-deploy marker longest. A transient `logs: <mode>` segment from a
 * Ctrl+L cycle leads the row when present and is kept longest of all. Segments
 * stay recoverable from the agent header in scrollback. Returns undefined when
 * no segment has content so callers skip the row.
