# Emotion Manager

Centralizes Synth's **emotional state**. It persists emotion intensities,
applies time-based decay so feelings fade naturally, and balances opposite
emotions on the Plutchik wheel. The current emotional state is injected into
every prompt so Synth's tone reflects how she feels.

Backed by the `emotion_state` and `emotion_diary` tables.
