/**
 * T010d — Conversation affinity can now go negative.
 *
 * The fallback-response path (and the AI affinity-application path) previously
 * floored affinity at 0 inside the conversation code, contradicting the global
 * -100..100 STAT_BOUNDS fix. A sour interaction must now be able to push affinity
 * below zero so a disliked NPC's negative feeling persists.
