Tenebrae's rubric replaces Matins' usual opening with a silently-said
Pater/Ave/Credo, live-verified against both Monastic Tridentinum 1617
and Divino Afflatu 1954 (Holy Thursday: Invitatorium and Hymnus both
"omittitur", no Ps 3 or versicle either). Since this app already never
renders that silent block on ordinary days either (data/hours/prime.yml),
the fix is a pure omission straight into Nocturn 1, using the same
isInTriduum window added for the Gloria Patri work.
