Replaces the FeastRank placeholder with a real ordered FeastClass (the old pre-1955 six-level scale) and a new TemporalCategory (privileged/ordinary Sunday/feria). calendar/commemorations.ts's decideOccurrence encodes the actual precedence rules as explicit, commented branches per category rather than the reference engine's own opaque numeric weights — this app targets one ruleset, so the readability trade-off is worth it. Category membership (data/calendar/temporal-categories.yml) is a best-effort reconstruction of the pre-1955 tradition, not sourced from a primary text; expect corrections. calendar/feasts.ts resolves real sanctoral candidates, and resolveDay() wires it all together — occurring/temporalCategory are no longer stubs. isDoubleOrHigher (hours/antiphon.ts) is now a real comparison instead of a hardcoded false. Seeded 7 real saints/feasts, each verified directly against Divinum Officium's own rank data (not reconstructed from memory) as a small, growable start: St. Lawrence, the Assumption, St. Augustine, the Nativity of the BVM, St. Michael, All Saints, the Immaculate Conception.
