tests/hours/matins.test.ts covers both branches (ferial, Sunday)
end-to-end through the real resolveOrdo mechanism against two clean,
live-verified dates — psalm/canticle counts, Te Deum presence, reading
citations/statuses, Gospel flagging and its Common-fallback exclusion,
and responsory matching.
tests/hours/prime.test.ts and tests/ui/shell.test.ts both had assertions
that Matins was still pending — replaced with assertions that it now
renders real content, mirroring the equivalent Compline test.
