The current project follows a "literate coding" approach where:
- Only Amp is allowed to make code changes.
- Commit messages need to be detailled and include the link to the last Amp thread.
- The Amp thread may have been handed off from previous threads, which can be explored.
Based on the commit history of the current project, explain:
Why does the `get_billing_period` function use these specific default arguments?

Let me check the original thread for the design rationale:
Read thread — Find the rationale for the 19th-18th billing cycle dates in get_billing_period - why was day 19 chosen as the start?
The 19th-18th billing cycle is Octoco's internal billing period structure. From the original thread, the user explicitly stated:
"We work on a 19th of the month to 18th of the month billing cycle, so costs incurred over that period is always a major talking point when it comes to invoicing."
The default arguments:
reference_date: date | None = None— defaults todate.today()so it automatically shows the current billing periodcount: int = 6inget_previous_billing_periods— provides 6 months of history for the dropdown selector
