"""Self-soothing: when the creature is low, it autonomously comforts itself with
an item — walks to it, carries it around — and gets a SMALL lift from doing so.

It gains far more from being cared for by people than from soothing itself, so the
self-administered Scores here are deliberately gentler than the user-triggered
toy/care Scores. This is throttled SERVER-side (one global soothe per cooldown),
so it fires once for the shared creature, not once per connected browser.

Honors the hard rule: self-soothing writes a real (if small) VADUGWI Score; the
carry animation the client plays is just the visible form of that real event.
