/**
 * `chatBubbleLiveStatus()` — default LiveStatusStrategy.
 *
 * Pattern: Strategy. Adapter for a consumer-supplied callback.
 * Role:    The "every chat UI" sink. Wraps a `(line: string) => void`
 *          callback so the consumer just hands us the function their
 *          chat-bubble component needs and we drive it on every
 *          rendered status update.
 *
 * Use when:
 *   - Building a chat UI (Neo, Lens, embedded widget) where the
 *     consumer owns rendering but not state derivation
 *   - Tier-1 of compose chains (`compose([chatBubble(setLine), stdout()])`
 *     so dev console mirrors what the user sees)
 *
 * The callback runs on EVERY status transition. Consumer can debounce
 * / coalesce per their needs (we don't impose UI policy).

     *
     * NOTE: this is INTENTIONALLY the only callback. If you need access
     * to the underlying `StatusState` (for color-per-state, animation
     * triggers, etc.), build your own `LiveStatusStrategy` directly OR
     * use `compose([chatBubbleLiveStatus({onLine}), customStrategy])`.
     * We don't surface `StatusState` here because it's an INTERNAL
     * shape — exposing it would couple consumer UIs to changes in the
     * state machine.
