+// efOracleDay is one day of missalemeum's per-date proper API, as captured in
+// sources/snapshot.tar.gz (missalemeum/en/YYYY-MM-DD.json, 2026-01-01 ..
+// 2027-12-31, 730 days) and flattened by scripts/build-oracle-ef.sh.
+//
+// Three things about this data that will otherwise cost hours (see that
+// script's own header for the full account):
+//
+// 1. ID looks like "sancti:MM-DD:rank:colour", but its embedded rank is the
+// rank of the PROPERS USED that day, not the day's own rank -- e.g.
+// 2026-01-02 is a class-4 feria carrying id "sancti:01-01:1:w" because it
+// reuses the Circumcision's propers. Kept here for provenance/debugging
+// ONLY. Rank and Colour comparisons below use Rank/Colours, never ID.
+// 2. Colours is an array -- 14 of 730 days carry two values (Gaudete/Laetare
+// "pv", Palm Sunday "rv", Good Friday "bv", Holy Saturday "vw") -- so the
+// comparison is membership, not equality.
+// 3. A two-colour value on a weekday can be an artifact of proper reuse (a
+// feria inside Gaudete/Laetare week reusing the Sunday's own propers)
+// rather than a claim about that weekday's own colour. No special-casing
+// is needed for this: lectio's single ferial colour (violet) is already a
+// member of the reused set (e.g. ["p","v"]), so a plain membership check
