/** The nudge text for a crossed band, specialized to the node's (mode,

 *  the single "keep going past this window" verb for every persona: it refreshes
 *  the node into a clean window, MODE-PRESERVING — a base node stays base,
 *  continuing fresh against its goal and its note. `--promote` is a separate,
 *  explicit opt-in (never steered here as auto-behavior) for when what remains
 *  has genuinely grown into phases to delegate across children — so no persona
 *  is ever steered at a bare `node promote` (which framed promotion as a heavy
 *  "become an orchestrator" step and bred yield-avoidance).
 *
 *  - orchestrator (terminal OR resident): checkpoint context/roadmap.md, then
 *    yield (it already has a roadmap to bring current first).
 *  - resident/base (root conversation): yield to continue fresh if the chat is
 *    growing into a job, else wrap up — a root can simply end.
 *  - terminal/base (worker): yield to continue if work remains, or `push final`
 *    when close.
 *
 *  The wording strengthens with depth: gentle < 150k → firm < 185k → pushy at/
 *  past 185k, where drifting further risks an overflow. */
