"""
Pure data transformation utilities for Tibber Prices integration.

This package contains stateless, pure functions for data processing:
- Time-window calculations (trailing/leading averages, min/max)
- Price enrichment (differences, volatility, rating levels)
- Statistical analysis (aggregation, trends)

These functions operate on raw data structures (dicts, lists) and do NOT depend on:
- Home Assistant entities or state management
- Configuration entries or coordinators
- Translation systems or UI-specific logic

For entity-specific utilities (icons, colors, attributes), see entity_utils/ package.
