The Info tab fills in — the board's vital statistics in two honest registers

Model facts off the live snapshot (Lanes, Cards with the trash's freight as a
quiet tail, Attachments — the welcome-count live-only rule) and disk facts off
one background whole-folder walk (File, Files, Size, Created, Modified — .git
and .trash included, so the rows agree with Finder's Get Info), with a Reveal
in Finder link as the door to the folder the rows describe.
