A project header now reads "fleet (13 of 38)" while Hide offline or Hide
seen hides at least one row, and "fleet (38)" when nothing is hidden. The
note under the table still says which filter hid how many. Numbers only,
so nothing new needs escaping. Static test pins the expression and the
removal of the raw-length header. Sonnet review: APPROVED, no findings.
