+(* RG 128, transcribed in docs/research/rules-register.md §3b: violet is used
+   for "II/III-class vigils outside Paschaltide". Two of colitur's five vigils
+   disagreed with that rule until the ef-oconnell-rubrics branch -- the
+   Assumption's (II class, 14 August) was White and St Lawrence's (III class,
+   9 August) was Red. Both are outside Paschaltide, so both are violet.
+
+   O'Connell, The Celebration of Mass 4th ed. (1964), section 4(c) states the
+   same rule and its footnote 169 names the sole exception -- "the only vigil
+   of II class within Eastertide is that of the Ascension and its colour is
+   white" -- which colitur already emits correctly (ef-ascension-vigil, white,
+   pinned by the two Rogation Wednesday cases just above).

+   Pinned in years where each vigil is actually OBSERVED rather than impeded:
+   9 August 2025 is a Saturday and 14 August 2025 a Thursday, both checked
