Pacing notes

From July 24 workshop:

|Time|Activity|

|0:00|Start|
|0:15|Talk start|
|0:50|Talk end|
|0:55|Break|
|1:00|Workshop start|
|1:20|Check-in, @ 5.2|
|1:30|Check-in, @ 6.5|
|1:45|Break|
|2:00|Check-in, @ 7.1|
|2:20|Check-in, @ 7.3|
|2:30|Closing check-in, @ 7.4.1|

Considering there are 14 chapters, there's _plenty_ of content here for 150-minute workshops. I think it might be able to go up to 240 minutes without a problem.

The issue only provides workshop pacing notes from July 24 and does not name a file or test. Start by locating the workshop schedule and its 14 chapters, then compare the current 150-minute plan with the proposed 240-minute duration. Done means the workshop pacing reflects an agreed duration and remains consistent with the chapter content.
