Session formats and roles
What kinds of sessions each program printed, and which roles its listings carry.
Many programs name a session's format, but each uses its own words. Roles come from the printed labels: chairs appear only where the program prints them, so a low chair count in 2019 or 2025 is a fact about the program, not the conference.
