• Time semantics note:
• bar.timestamp is a UTC nanosecond timestamp.
• bar.timestamp_iso is a UTC ISO 8601 string.
• self.now, self.to_local_time(...), and self.format_time(...) are the recommended display-layer helpers for local timezone rendering.
• A Beijing market close such as 2023-01-03 15:00:00+08:00 may therefore appear as 2023-01-03T07:00:00Z in structured fields. This is expected and represents the same instant.
