 The tool is a Flask application that Canvas launches over LTI 1.3. A
 single URL serves everyone: Canvas identifies the person and course on
-each launch, so instructors get the call-list and reporting views while
-students get the absence form and their own history. The roster comes
-from Canvas through the Names and Role Provisioning Service, which means
-adds and drops are picked up automatically rather than reconciled by
-hand.

-Selection uses the same weighting as the manual system it replaces: each
-answered call divides a student's weight by the course's weight factor
-(default 2), so students who have answered more questions become
-progressively less likely to be called. Each course can instead use
-"cycle" mode, a rolling rotation through the roster in random order:
-everyone is called once before anyone repeats, batches take the next
-students in the current pass (continuing across lists and class days),
-and skipped calls don't count as a turn. These, along with whether
-students can see their own assessments, are per-course settings.

 ## Daily use
 
 The instructor page works against a selectable date (defaulting to
 today), so printing tomorrow's list a day in advance just means
-switching the working date. There are two ways to run a class, per
-day and freely mixed:

 - **Live mode**: a "call next student" button shows who's up (photo,
