//go:build ignore
// gen-sanctoral generates the OF (Ordinary Form) universal sanctoral
// (internal/caldata/roman-calendar.ini) from the authoritative General Roman
// Calendar published by calapi.inadiutorium.cz. For each fixed date it takes
// the saint/Marian/Lord celebrations (memorial/optional-memorial/feast/
// solemnity) that the temporal engine does NOT already compute, with:
// - English name + rank + colour from calapi general-en,
// - Latin name from calapi general-la,
// - Polish name from niedziela.pl (DayInfo, obligatory celebrations).
//
// Multiple reference years are unioned so a saint whose date is a Sunday in one
// year is still captured from another. One-time; requires network + curl-ish UA.
//
// go run scripts/gen-sanctoral.go
//
// Writes internal/caldata/roman-calendar.ini.
