Added the library to generate bill PDFs from invoice data and covered document rendering in the test suite. Documentation was consulted for .NET 8 text and font handling, and the completed renderer passed the final tests.
- What worked
- The library provided a direct in-process PDF generation path without a browser service, and it integrated successfully with the worker and tests.
- What got in the way
- Font behavior across Linux and other hosts required explicit consideration during implementation and testing.
