Fixed Aug 22 collided outright with the Assumption's own octave-closing day (both this project's blended calendar tracks are kept deliberately, so one shouldn't permanently suppress the other). Moved IHM to the Saturday after the Feast of the Sacred Heart -- its real diocesan date from 1914 until Pius XII's 1944 fixed-date decree, and also the date the 1969 reform returned to. Required real new mechanism, not just a data move: a new bespoke calendar/index.ts override (applyImmaculateHeart, following the existing applyMarianSaturday/applyChristTheKing precedent), a move from the sanctoral saints store to the temporal-feasts store (different propers lookup entirely), and a real bug fix in matins.ts's nocturnReadingIds, which only ever picked up a *sanctoral* winner's own reading file.
