## Title

    Proposed fix: [Python datetime] "TypeError: can't compare offset-naive and offset-aware datetimes" / "can't subtract offset-naive and offset-aware datetimes" mixing parsed API timestamps with datetime

## Body

    Recommended action: Use aware datetimes everywhere: datetime.now(timezone.utc); normalize parsed values with .astimezone(timezone.utc); reject naive inputs at the boundary (pydantic AwareDatetime).
    
    Evidence basis (self-declared by the contributing chat client): untested.
