Other campuses set themselves up: one install line, one join line per computer, keys made from what is found

settings/discover.py reads Companion's connections (and their addresses and channel counts), the
Dante devices, the network MIDI sessions here and on joined Macs, this Mac's wired network, and
what runs on each joined computer. settings/autoconf.py turns that into keys, checks, start and
restart fixes and a page layout the way North Attleboro's were made (group keys only when not
everything fits; receivers fold first), all through the existing builders and rules.
settings/campus.py prepares Companion through its internal API (the panel's custom variables and
the blink trigger), picks free pages, applies the first config, serves the program kit, the
campus install line and the Mac/PC join lines, and looks every ten minutes to add new gear
(discover.auto; never during a service or a recording, never removes, never re-adds what someone
took off). Settings > Auto-setup shows what was found and the lines to paste. install.sh keeps the
kit and makes the panel's login key.

Checked on North Attleboro read-only: discovery finds all 43 connections, 19 Dante devices, four
Macs' MIDI sessions and seven computers, and a from-scratch build reproduces NA's layout. The
Companion calls were tried with a throwaway variable and a disabled trigger, then removed.
